Unformatted text preview: @ HA D (a) What is K b for the hydrolysis of the conjugate base A-? (b) What is K neut for the neutralization of the acid using OH-? (c) How are K a , K b , and K neut related? 3 Problem: Buffer Solution (a) What is the pH of pure water at 25 C? (b) What would the pH be if 0.10 mL of 12 M HCl was added to 100 mL of pure water at 25 C? (c) What is the pH of 100 mL of NH 3 /NH 4 + buffer solution at 25 C if [NH 3 ] = [NH 4 + ] = 0.20 M? K b (NH 3 ) = 1.8 10-5 . (d) What would the pH be if 0.10 mL of 12 M HCl was added to this buffer solution at 25 C? 4...
