1. Determine the molar solubility of Cr3+& OH- ions in the compound Cr(OH)3 at 25oC at:

a pH of 7.9

b.0.010 M chromium (III) nitrate

c.Distilled water

The Ksp is 6.30 x 10-31

2.A solution is prepared by mixing 0.050 M Pb(NO3)2 with 0.00350 M KBr.

a. Determine where this solution will be unsaturated,saturated or super saturated.

b. Write a balanced net ionic equation for this chemical reaction.

3) The Ksp for PbBr2is 6.6 x 10-63.Calculate the solubility Ag2CrO4(s) in a 0.100 M solution of AgNO3 and compare its solubility with Ag2CrO4 solubility in purewater at room temperature. The Ksp for Ag2CrO4 is 9.0 x 10-12 at room temperature. The Ksp for Ag2CrO4 at room temperature in pure water is 1.3 x10- 4
