Concentration of AgNO3 to reduce solubility of Ag2CO3
Perez Jessica Thomas Gary Thompson Betty
What if in question they gave us [Ag]=2.56×10^-4 And we have to get ksp of Ag2CO3?
bro i hate my life this is too difficult.
oh my gosh thank you for this post. i'm 60 yrs old and i couldn't remember my high school chemistry class...sorry Mr Lehman!
Well explained !
what if the meniscus is convex? Do we measure the highest point then? what if the liquid is colorful? One of my teachers said then we measure the highest point on concave meniscus (doesn't have a lot of sense) was she right?
شكرا ايها الرائع
Thank you so much
Nice video Mark. :)
Does te pH increase because of the increase in volume?
Yes, a little, but the majority of the increase is because now we have more of the weak base, and less of the weak acid present
And so please tell me how, how im supposed to remember the tiniest fraction of a space on something ive never seen before, something is wrong with you intergrated science teacher...........
You explained very well. Thank you so much👍🏻👍🏻👍🏻
Fantastic..which program you use
12.8
Thank You Mr.Mark
thank you, mark
Slay ❤
I don’t understand how !!???? It just lines 😓
at 1:17 isnt fe3+ yellow ?
THANK YOU
this really helped me thank you so much
This is the only video that helped me understand thank you SOOOO much!!!
❤🎉
my professor linked this video
bro- idk if this was supposed to be a tutorial or something but it's not, Do YOUR WORK BETTER
I saw this conducted by Dr. Luther K. Brice of Virginia Tech in 1973. He had been conducting this for years before 73. He was the best teacher I ever had in my life. A great man.
You have confirmed to me that somehow I have retained knowledge given to me in the 7th grade thank you sir and thank you Mrs. Stringfield 7th grade physical science.
This help me A lot
thank u! Also, do u have any video about basic medium?
Thanks for this. Great explication. It did what my teacher could not
Hi i would like to know from anyone who knows, why or how, when we calculate initial molarity of I- , we do not divide by two moles. In the equation it is written 2I-, that is why it is a bit confusing. What is the pattern I am missing? How can it be explained?
Hi, for the iodine clock reaction, rate has been experimentally found to be rate = k[Iodate][Bisulfite], hence we can simply use the iodate concentration without dividing it. Usually, dividing it by the coefficient in the equation is solely for stoichiometric calculations.
Thank you Blaser! As always easy to understand and thorough explains. :)
This 5 yrs old video saves me from my report that is due today 🤣🤣
Instead of doing it yourself, just go watch someone who already knows how!! Pass the buck. Everyone is doing it these days!! You’ll never learn what others put the time in to learn! Yeah!
@@skiphoffenflaven8004 You can't always "do it yourself" if you don't know the proper methods. People learn by example, not by magic.
As you can read, I am still confused-
exactly
Thank you!
I still dont understand- 👁💧👄💧👁 why does this have to be so hard
BRO SAME
I just don't understand how you can add these decimals and stuff when they're literally just unlabeled lines...
Very nice explanation!!
Still don’t make sense
exactly
The volume on the sounds effects were a little too loud.
why does the curve go back up? does the temperature increase again? If yes, why?
Teacher why
i am here cuz of school
how did you get the total 11ml as a final volume
by adding the volumes of all substances
Would you like to tell me which app you are using??

Hello everyone watching this video from 6th period science. I love you all
You are amaziinggggg .... THANK YOU
Thank you much
How did you get the 0.200M at 4:09? what did you add or whatever to get that 0.200M
It is a given.
what would the units for k be?
