This channel is so underrated! Thank u so much for these videos! I’m watching all the ones in the playlist , they are extremely helpful and very easy to understand
Hi, I really liked this video, It is clear and very good, but I have a question: Why do you use Ksp = 5.5*10^(-5) while all the data about Calcium hydroxide say 5.something*10^(-6)? When I repeat the calculations with the available data from different institutes, the solubility I obtain is 0.79g/L, while the correct value is around 1.7g/L. Where did you get the Ksp data? And why the "correct" Ksp value does not give me the correct solubility? Thank you!
Hi Paolo, I am sure I just looked up the Ksp for Ca(OH)2 on a table. Maybe I misread it. You can Google or look in textbook tables for salt Ksp values. Ask your professor which table they prefer you use! Thanks!
