(a) Calculate the molar solubility of AgI in pure water. Ksp for AgI is 1.5% 10-16 mol/L (b) Calculate the molar solubility of AgI in 2.3 M NH3. The overall formation constant for Ag(NH3)2+ is 1.7 x 107 mol/L (c) Compare the calculated solubilities from parts a and b. O The molar solubility of AgI is two times greater in ammonia than in pure water. O The molar solubility of AgI is two times greater in pure water than in ammonia. O The molar solubility of AgI is greater in pure water than in ammonia. O The molar solubility of AgI is the same in pure water as it is in ammonia. Explain what occurs upon addition of NH3. O The presence of NH3 decreases the solubility of Ag.
