The overall Kf for complex ion Ag(NH3_x+ is 1.7 x 10^7. The Ksp for AgI is 1.5 x 10^-16. What is the molar solubilitiy of AgI in a solution that is 2.0 M in NH3?
A buffer solution is prepared by dissolving 1.50g each of benzioc acid C6H5CO2H and sodium benzoate NaC6H5CO2 in 150.0mL of solution.
Explain possible reason for discrepency between the actual pH of the buffer and the reported pKa of the weak acid. (My case: actual pH =9.23, reported pKa =9.25)
