1.The observed solubility of the salt MX in 4.0?M?strong acid is 2.30 x?10?3?M.? The?Ka?value for the acid HX is 1.00 x?10?9.? Calculate the value of?Ksp?for the salt MX.

2.Consider a solution made by mixing 500.0 mL of 4.0?M?NH3?and 500.0 mL of 0.40?M?AgNO3. Ag+?reacts with NH3?to form AgNH3+?and Ag(NH3)2+:


Ag+?+ NH3??AgNH3+ K1?= 2.1 x?103
AgNH3+?+ NH3??Ag(NH3)2+ K2?= 8.2 x?103
