Question

For each of the salts on the left, match the salts on the right that can be compared directly, using Ksp values, to estimate solubilities. (If more than one salt on the right can be directly compared, include all the relevant salts by writing your answer as a string of characters without punctuation, e.g, ABC.) 1. aluminum phosphate A. Mn(OH)2 2. magnesium hydroxide B. AgBr C. CuS D. MgCO3 Write the expression for K in terms of the solubility, s, for each salt, when dissolved in water. aluminum phosphate magnesium hydroxide Ksp

Answer 1

Answer:

1.AD

2.BC

Explanation:

For aluminum phosphate AlPO4 (s) <------> Al^3+(aq) + PO4^3-(aq)

Ksp= [Al^3+] [PO4^3-]

For magnesium hydroxide

Mg(OH)2(s) <--------> Mg^2+(aq) +. 2OH^-(aq)

Ksp= [Mg2+] [2OH^-]^2
