If a solution has [Cu+] = 4.5 x 10^-5 and [Br-] = 3.4 x 10^-5, and Ksp of CuBr is 5.3 x 10^-9 is it saturated?

Question

Also, is the solution supersaturated? Or, is it unsaturated? Will the solution form a precipitate?

Thanks in advance for your help!

Answer 1

Write the Ksp expression for cuprous bromide
[Cu]+ [Br]- = Ksp
Substitute in your numbers
4.5x10-5 x 3.4 x 10-5 = 17.2 x 10-10 or 1.7x10-9.
Since this is less than Ksp, the solution is unsaturated, and will not precipitate any solid cuprous bromide.

Answer 2

yes, what are you crazy. the answer is yes. that one is a little easy. but in time u shall get butter
