Will these salts produce acidic, basic, or neutral solutions in water?

How can you predict whether a salt will produce an acidic, basic, or neutral solution when you dissolve it in water?

No no no. Just memorize the small list of strong acids. Everything else is weak.
^^ This isn't 100% true but works for most students in high school / university :)

[@peterrivera9851]

Anyone wondering why the conjugate acid SO4^-2 is H2SO4, remember that it is reacting with two NH4+ which both give it 1 H+. Consequently it's conjugate acid is H2SO4, which is one of the 6 simple, strong acids. You can find a chart of all six of these thru google (there a good thing to memorize).

[@lilykarg6617]

this helped so much !! i've been struggling with this concept all semester, and our final exam is tomorrow. it makes so much more sense now, thank you !!

[@haiderlakhte7270]

How

[@jonahupah5377]

This video somehow explained the salt thing in a way I understand. Thank You

[@getitdone0010]

THANK YOU!!!! I have MCAT coming up.....Your videos literally helps 24/7

[@user-yd8xq7tb5u]

I am from India and I suddenly found this vdo..which clear my concept easily.thanks a lot

[@OShawna23]

🎉🎉🎉 thank you for helping me study for my MCAT ❤

[@cougarfanforever]

studying for an exam and this helped a ton! You rock!

[@benjaminshepler9616]

The first example is incorrect. The conjugate acid of sulfate is HSO4-. While H2SO4 is a strong acid, HSO4- is not. The second proton in sulfuric acid only partially dissociates. For this problem you need to consider the Ka of NH4+ and the Kb of sulfate. You would have to solve this problem like his part c).

[@cynthiar3013]

So..... was B a basic solution???

[@kshiprajadav179]

Yup!

[@AbsoluteFunction]

Thanks brother. Made it so much simpler and shorter than my prof did.

[@NickVetter]

I like how you explained it more instead of just saying well this is acidic because that is blah blah blah

[@alsween218]

This was awesome! I got an exam tomorrow and this is going to be on it. Very helpful and informative. Thanks for posting :D

[@jherollsayban]

i love this chemistNATE guy...

[@EditsbyNicole]

I used two of your videos so far and i understood both concepts completely after watching! Thank you so much!
P.s. can you be my chemistry teacher?

[@Cramerica66]

Thank you for your time. This video is great.

[@027dramaqueen]

literally only video that helped...thank god

[@Naveen-iu7eu]

Finally i understood this, thank you so much.

[@moximuss]

Im in med school and this video is still super helpful.. Thank you Nate.

[@medadrufus]

absolutely useful and clear!

[@PankajKumar-em7sb]

Nice explanation

[@TheLarBear94]

this dude literally saves my GPA

[@bread_couch7118]

Thank you. I finally understand something.

[@drinksoymilk007]

Thanks, Nate.

[@nancy3440]

Very well explained, and loved how you weren't speaking too fast. Thank you!

[@MangoMilkshake]

And THIS didnt help at all.

[@JesusChristIsLord__]

Oh my flippin god! You have a gift for instruction. This has been a mystery to me until you explained it. Thank you Thank you Thank you!!! Subd and liked !!

[@kingsean96]

LMFAOOO
It was all professional then you were like, "That's a legit equilibrium that happens"
I laughed so hard. Keep it up this helped me a lot!

[@Hardstyler981]

legit is a word, but how people use it now makes it like "unprof"

[@pamithkariyapperuma4449]

Mate thank you so much that was really good love ya !

[@chanteltaylor3531]

Thanks -- Very very helpful

[@luevang4113]

Thank you, Mr. chemistNATE. Your explanation was 200% better than how my book tried to explain it. Again, thank you very much, and I've only skim your other videos, but I'd like to encourage you to keep up the good work :)

[@deathscape10]

Sulfuric acid is a strong acid; HSO3 is the weak conjugate acid for the base SO3.

[@mushimushinomi]

you're good, no you're great actually

[@carolmery]

you are a life saver! I understand this now

[@emilekight5836]

For the second example, is the solution basic because its salt of a weak acid and a strong base (spectator ion only)? A lot of other people seem to get fuzzy on that part...

[@leticiamartinsdearaujo4982]

you're my hero :)

[@qaboosmintaka5337]

dammit missed this question on the test. The question was worth 20% of the test!!!!!

[@GabeyGalindo143]

Very helpful, thank you!

[@saisdhongade1656]

thanks Nate!!!

[@Arijana2010]

Thank you that was incredible! Really helped me so much!!!!!! THANK YOU!!

[@junholee1725]

Hi! uhhh I would like to know the reactions happen when salts dissolve in acids such as calcium oxalate dissolve in certain acids? Could you explain please? I was searching for it ages online

[@jt21419]

I wonder how CN- can have its own Kb since it has no OH- to dissociate into.

[@Wosjb78]

lol unfortunately in the IB Chemistry higher level exams they don't give you the Ka/Kb values so if you get a nasty one like the last one you did in the video we can't really tell which dissociate more and thus whether the solution would be basic or acidic. Oh well... Good concept though. It works

[@steveo9919100]

Is he Irish!? Great video keep up the awesome videos!

[@templar19]

For example a:
Couldn't you just take the Ka of NH4+ (which is in the order of 2*10^-5), compute the Kb of the sulphate ion (which, given the Ka of HSO4, puts the Kb in the order of 10^-12), and argue that, given the relative magnitudes, such a solution would be acidic?

[@platonslinko]

thanks, helped very much

[@jessielisaa]

Thanks for a great video! I have had a hard time finding anything on the intrenet about this topic but luckily I found your video! :)

[@ervinabajrami]

Thank you!

[@dendogg55]

Thanks dude.

[@tb2748]

dumb questions incoming.
we saw in the first example that clearly NH4+ could donate a proton, allowing for the salt (NH4)2SO4 to be acidic. and given that the SO4^2- ion will not accept protons because it is the conjugate base of a strong acid.
but how can a salt like CuSO4 be acidic if it has no protons to donate? and if you want to be technical, only the first proton in H2SO4 is strong. the second proton dissociates less easily, making the second one weak. wouldn't that allow SO4^2- to accept at least one proton (making it slightly basic)?

[@chemistNATE]

The Cu+2 ion of CuSO4 is acidic for a special reason. In water in becomes Cu(H2O)6(2+) which is a “complex” (H2O are ligands) and so it does actually have an H to donate

[@chemistNATE]

HSO4- donates more H than it accepts (you are correct that it can accept). Overall it will be acidic because a higher % of the H’s are donated vs accepted back

[@nCzFx11]

THANK YOU SO MUCH FOR THIS. NOW I SHALL PASS.

[@sakonpure6]

Very well put, thank you!

[@KrokoDerDino]

Spanishiwa liked it, so i thought it's bout Starcraft. x)
But nice guide. ;)

[@anupanadarajan4175]

Doesn't a strong acid/base have a conjugate base/acid that is neutral?

[@Starburstluver69]

thanks bestie

[@dave45032]

Welp. Further confused me.

[@ruthrodarte4552]

what was first one ? neutral?

[@julietivanov4915]

super helpful! thanks :)

[@DC-zi6se]

How do we know an acid is weak or strong??

[@nabarajbaral2063]

Why NaHSO 4 is a salt however it is slightly acidic?

[@trippypixie1]

So was the solution for B) basic or neutral?

[@haiderlakhte7270]

Nooo

[@TheReefsurfer]

great job thanks

[@MaurtreRS]

Thanks.

[@TinbitYoseph]

King fr

[@Fleato]

what the actual is being said here. like. i feel like chemistry at this point just says things happen and expect that everyone taking chem is jsut going to educated guess. " yup this is the point where we seperate into different things"

[@chemistNATE]

Let’s figure out where you’re lost.
* do you know what HF does in water ?

[@TheObservingViewer]

Thanks

[@melo9490]

Are you Canadian? And was the second one basic or acidic?

[@sweatyNate]

thank you

[@Dianity900]

so i have to memorize weak bases/acids tooo?

[@johannisbeerejoghurt]

protone sucking up ability :D

[@dinamn1549]

how do you determine the conjugate pairs that you hv written in orange ? pls help ! :(

[@duhduhduhdavid]

thanks!
and btw nice watch!

[@germanwizard]

@ 3:28 you said H2SO4 is a weak acid, the example you did right before it had H2SO4 as a STRONG acid with SO4 as a weak base... Im confused.

[@TwistedPencils]

H2SO3 was the second example :)) not H2SO4

[@benjaminthomas8988]

How can H2SO4^-2 be a strong acid in the first formula and then be a weak acid in the second?

[@Ats0Cool]

+Benjamin Thomas That's because in the second formula it was SO3^2- and not SO4^2-

[@benjaminthomas8988]

What? Cool thanks

[@NkanyisoMthombeni]

you have the same accent as my physics lecturer

[@Medi-Nor]

👍🏽U really goo at explaining chemistry topic/ but this one I still don get it/ is there's a easy way
To explain it.

[@Wolfeywolf16]

Thought i got it....till i came here.

[@579093]

So what did b. make?

[@soodmm13]

chemistNate: saving my ass since my freshman year of HS to my first year in college :P.

[@carlosjr746]

New drinking game: take a shot after every time he says "this"

[@delsol7878]

Ka for HSO4- is 1.2 x 10^-2. It does not dissociate completely.

[@JasmynLaw]

There was a lot of "sucking".... haha

[@jayeonkim1354]

awesome !!!!

[@anayanez187]

could I just borrow your brain for my midterm?

[@alizeyzahra4947]

I don't understand

[@danieltirsoreanu2152]

Thank you so much!

[@bollitodefresa]

Thanks *w*

[@Zen-ow8xf]

Its difficult to understand

[@JesusChristIsLord__]

"proton sucking up ability" love that man. I need layman terms not some stuffy professor's explanation!

[@Wolfeywolf16]

Ummmm.......

[@DragonLowStar1]

terrible video, doesn't even answer the questions

[@gagewilson6428]

wrong

[@quietethecamper]

It explained the concepts very well and walked us through several typical questions relating to the topic and provided the answer. What is wrong with it?

[@hmz01_]

lol wat r u on about

[@tremainkendrick706]

Did not get this at all!!!

[@RishavRaj-yi5ys]

Aur chotta page nhi mila tha

[@579093]

Nvm great vid :)

[@PossessedPanda]

thank you for the information but I have to let you know your tone of voice sounds unbearably condescending in this

[@niecythegreat]

Oh :/ I thought he was just being excited

[@pamithkariyapperuma4449]

if u increase speed up to *2 then he sounds nice and enthusiastic

[@maimaymay1913]

Not helpful. I got even more confused after watching this.

[@sachinkumarkumar6538]
