Will the solutions for Test 2 be posted? I think they'd be helpful for better understanding the material.

Only Q9 is covered in the final.

Q9 Answer


Kc/[OH^-]^2 =[Ca^(2+)]

(5.5 x 10^(-6))/(3.2 x 10^(-2) M)^2 =[Ca^(2+)]

[Ca^(2+)] = 54 M (Please note: The solubility of Ca2+ cannot (in reality) be this high.]
