A solution of 0.0470 M HCl is used to titrate 29.0 mL of an ammonia solution of unknown concentration. The equivalence point is reached when 15.5 mL HCl solution have been added. (Assume Kw = 1.01 ✕ 10−14.)

(a) What was the original pH of the ammonia solution? WebAssign will check your answer for the correct number of significant figures

(b) What is the pH at the equivalence point?
