The solubility of an unknown salt,MZ_3, at 25°C is mol/L.What is the K_sp for MZ₃ at 25°C? E)none of these

Question

Quizplus · Accepted Answer

The formula for the solubility product constant (Ksp) is as follows: 
Ksp = [M+][Z-] 
Since the salt is likely ionic, it can be assumed that the formula will dissociate in solution into M+ and Z-. The solubility of the salt is given as 11eaa8f0_66de_1815_93a6_0f812184b9b0_TB6423_11 mol/L, which represents the concentration of both M+ and Z-. Since both M+ and Z- will have the same concentration, the Ksp can be calculated as follows: 
Ksp = (11eaa8f0_66de_1815_93a6_0f812184b9b0_TB6423_11)^2 = 11eaa8f0_66de_1817_93a6_f1bc2022c716_TB6423_11 
Therefore, the correct answer is B.
