Q1. Calculate [Ag+] present in a solution at equilibrium when concentrated NH3 is added to a 0.01M solution of AgNO3 to give an equilibrium concentration of [NH3] = 0.2M.
Q2. Silver chloride usually does not ppt in solution of 1.0M NH3. However AgBr has a smaller Ksp. Will AgBr ppt form a solution containing 0.01M AgNO3, 0.01M NaBr and 1.0 M NH3? Ksp = 5 x 10^-13
Q3. Calculate the molar solubility of AgBr in 1.0 M NH3?
ANSWER
Q1. 1.5 x 10^-8
Q2. 6.1 x 10^-12
Q3. 2.9 x 10^-3
