For each of the salts #1 and #2, match the salts A,B,C,D that can be compared directly, using Ksp values, to estimate solubilities.

(If more than one salt can be directly compared, include all the relevant salts by writing your answer as a string of characters without punctuation, e.g, ABC.)

1. Barium Sulfite

2. Magnesium Hydroxide

A. MnCO3

B. Fe(OH)2

C. Ag2SO4

D.Ni(CN)2


Write the expression for K in terms of the solubility ,s, for each salt when dissolved in water. Example : 4s^2 or s^2

Barium sulfite_____

Magnesium hydroxide _____

Homework Answers

Answer #1

Barium sulfite = BaSO3

BaSO3 -----> Ba2+ + SO32-

so salt that can be compared with it will be, A

MnCO3----> Mn2+ + CO32-

2.Magnesium Hydroxide = Mg(OH)2

Mg(OH)2 ----> Mg2+ + 2OH-

so salt that can be compared with it will be B and D

B.Fe(OH)2 ----> Fe2+ + 2OH-

D.Ni(CN)2 ----> Ni2+ + 2CN-

Expression for K

barium sulfite-

BaSO3----> Ba2+ + SO32-

s s

so, K = [Ba2+][SO32-] = s.s = s2

Magnesium hydroxide

Mg(OH)2---> Mg2+ + 2OH-

s 2s

K = s.(2s)2 = s.4s2 = 4s3
