17.4 Solubility and Ksp | General Chemistry
Вставка
- Опубліковано 5 сер 2024
- Chad provides an introduction to solubility equilibria with a comprehensive lesson on Solubility and Ksp. This begins with an explanation of how Ksp, the solubility product constant, is the equilibrium constant for a reaction in which a solid salt dissociates into aqueous ions. It is demonstrated how to determine the reaction for any salt as well as how to write the equilibrium constant expression.
The molar solubility is also defined as the molar concentration of salt that dissolves in water. The relationship between Ksp and the molar solubility is determined for a variety of salts, and it is shown how to calculate the molar solubility from the Ksp and the Ksp from the molar solubility.
I've embedded this playlist as a course on my website with all the lessons organized by chapter in a collapsible menu and much of the content from the study guide included on the page. Check this lesson out at www.chadsprep.com/chads-gener...

Thank you for taking time to explain the concepts and not just trying to show off your chemistry knowledge like all my undergraduate professors. You are a truly a Chad.
You're welcome and Thank You!
This is the one. Seriously!
Chad is the man! He clarifies everything that my professor skims over and I understand it perfectly. Can't thank you enough! ❤
You're welcome and Thank You!
I've watched so many Chad's Prep videos I'm starting to develop a parasocial relationship!
Next will be to take on my hairstyle!
My chemistry final is today... I really, really needed this!
Glad the video helped, Sarah - hope you do well!
Chad I have watched about a dozen or so people that teach the same material but you are hands down the best at this. Thank you for saving me!
You're welcome Tyler and thanks in return! Glad you find these helpful!
Thank you so much you have helped me numerous times over these past couple of months. I cannot stress how much you have helped me and peers, I am so thankful for your hard work and ethic. Beautiful explanation and examples love it!!
Glad to hear it, Nyte!
Im amazed i havent come across this channel earlier, the energy is amazing and its really helpful, the perfect pace! I will definitely come back to this channel for chemistry help
Glad you found us!
Brillant Teacher! So well explained.
Thank You!
Thanks for making this video! Amazing explanation, you have made my brain bigger!
You are welcome - And thank you!
I love the way you explain things, thank you.
Glad to hear it - You're welcome.
Very good explanation thank you very much, Chad.
You're welcome and Thank You.
My good sir, you deserve all the good things in the world 🙏🏾 explained so so well
Thank you for saying so.
I struggled on this unit and this video has helped me tremendously!!!!!!
Great to hear!
Thank you very much! While I am quite familiar with the topics explained, my brain tends to be quite scattered and often I get lost in my own calculations or mix-up what I was supposed to be solving for in the first place. Your way of organizing is helping me so much with keeping everything on track.
Glad the channel is helping - Happy Studying!
now one word is more than enough to describe you A " legend" ......thank u for your effort
You're welcome and Thank you!
What the actual fuck??!?? You’re telling me someone who teaches like this acc exist cuz there’s no way i’m acc understanding this concept. Gen Chem final coming up, life saver. Really wish i found this teacher earlier❤❤❤
Hope you do well on your final.
excellent teacher.. thank you so much for doing what you do
You're welcome and Thank You.
The last part of this video is worth is worth watching the entire video even if someone understands ksp. Tomorrow I have an exam and I know the professor will throw this question at us.
Thanks for saying so, Jimmy - hope you do well on your exam!
Thank You guys.
You're welcome.
Wow, you saved me! Thank you!
You're welcome!
How do you get those zeros ,and x ,x things,am getting the concept but those zeros and x are my barrier
I Enjoyed this 👌🏿
😀😀😀
THANK YOU!!!
You're welcome.
I love you chad
Glad you found the channel - Happy Studying!
Thanks 🙏
You're welcome
Nice sir thank you so much sir.
All the best
Thanks ❤
You're welcome!
Hardly need .. thanks 👍
You're welcome.
I'm having trouble solving a problem given to me from class. Is Kc the same as Molar solubility??
Here's the problem given:
The molar solubility of Magnesium Phosphate is 5.25 x 10^-6. Determine the concentrations at equilibrium if the initial concentration of the salt in 0.48M.
Chad, I love you
Glad the channel is helping you!
Thankk you
You're welcome
Hello, sir. What will happen to the solubility of BaSO4 if NaCl is being added, and why? Thank you so much.

Solubility of barium sulfate in sodium chloride solutions from 25° to 95°
Templeton, Charles C.
Journal of Chemical and Engineering Data (1960), 5 (), 514-16CODEN: JCEAAX; ISSN:0021-9568.
The molal concn. soly. product (K'3) of BaSO4 in the BaSO4-NaCl-H2O system was detd. from 25° to 95° and NaCl molalities of 0.1 to 5.0 as part of a study of scale formation problems from highly concd. brines from oil wells. Ba was detd. spectrographically and total S by a microreduction-colorimetric method. K'3 was found const., within exptl. error, at const. NaCl concn. and const. temp. with varying molalities of Ba++ and SO4--. K'3 increased with increasing NaCl concn. and increasing temp. (K'3)1/2 ranged from 1.08 × 10-5 at 25° to 1.68 × 10-5 at 95° with no NaCl and from 17.7 × 10-5 at 25° to 39.7 × 10-5 at 95° in 5 molal NaCl. Activity coeffs. in the BaSO4-H2O system, calcd. from the Debye-H.ovrddot.uckel limiting law, were used to get activity soly. products (K2). The activity coeffs. were compared graphically with those of ZnSO4, MgSO4, and CaSO4 in the ZnSO4-H2O, MgSO4-H2O, and CaSO4-NaCl-H2) systems, resp.
Sir one doubt? Are you covered advanced organic chemistry in your organic chemistry Playlist? It's enough for any competitive exams? Because I reading your lessons only.
The playlist covers a standard 2 semesters of undergraduate Organic Chemistry (Organic Chemistry I and II). At my university we also had some advanced organic chemistry courses that were graduate level courses, but this playlist would definitely not be sufficient for those courses. Hope this helps!
@@ChadsPrep ok ok sir.
Chad I am still stressed out from learning science!!!
Love from India
Thanks from USA
Never thought Walter White would help me solve chemistry
I hate Chem but I need it :(
I hope the videos/channel helps!
this is not kerbal space program!
