... " and then I swore a whole bunch of times.... " lol that's me when I work on aleks problems and get the rounding wrong.

Along with the Ksp value, the molar mass of CuBr is incorrect. The correct molar mass is 143.45 g/mol

I wish I would have read the comments before copying that into the final one on my Alex now I gotta get 3 more right to be done😢

On the second problem, for in pure water, the ksp for CuBr is 6.27x10^-9

You're videos are so helpful and save my life every week. It always seems so complicated until I watch. Thank you!!!

You are welcome Kaydi! I'm going to start making videos again so feel free to comment on any topics you'd like me to cover. I won't always be able to make them right away, but I'll try!

The answers for the first one are "1.6 x 10^-2 g/L" and "7.5 x 10^-6 g/L" using the ksp value Aleks gives btw.

Hello, do you have a video for this topic "Calculating the solubility of an ionic compound when a complex may form"? Thank you soooo much!!!

Hi Yeny! I just made this video for you: kzread.info/dash/bejne/lJWCybqAf7S7qZs.html Thanks for the request! I'm going to start making videos again as time permits. Good luck studying!

Why is it that in the second problem you don't have to square the second term whenever you are solving for x in the pure water portion of the problem?

do you mean with NaF or in just pure water? Because I'm pretty sure for pure water, you have to square. For NaF, we use small x, so only the constant (0.006) is significant.
