A solution of 0.0480 M HCI is used to titrate 27.0 mL of an ammonia solution of unknown concentration. The equivalence point is reached when 16.0 mL HCI solution have been added. (Assume Kw 1.01x10-14.) (a) What was the original pH of the ammonia solution? (b) What is the pH at the equivalence point? (c) Draw a titration curve for this titration. (Your curve should be quantitative; calculate the pH at different points to construct an accurate curve, not just a generic sketch.) pH 12 pH 30 10 25 10 10 15 Volume HCl added (mL) 20 25 30 6 Volume HCl added (mL) 10 12 pH 12 pH 12 10 15 Volume Hl added (mL) 20 25 30 10 15 20 25 30 Volume HCl added (mL)
