 3) a) What is the pKb for a weak base if the pH of a 0.125M solution of this weak base was found to be 8.16?

 4) When a weak acid is added to water to make a 0.250M solution, the acid was found to be 1.5% ionized. What is the Ka and pKa of this weak acid?

 5) At 60°C, Kw = 9.6x10-14 (Kw increases as the temperature increases). a) For pure water at 60°C, what is the [H+] and pH. b) If a sample of an aqueous solution was found to have a pH of 7.00 at 60°C, is this solution acidic, basic, or neutral given your answer to a)?
