Indicate whether or not each of the following ionic compounds will undergo hydrolysis and predict whether the resulting solution pH will be acidic, basic, or indeterminate (both ions undergo hydrolysis).

(a)    Sr(ClO4)2

acidic hydrolysis

basic hydrolysis

indeterminate hydrolysis

no hydrolysis

b) CaSe

acidic hydrolysis

basic hydrolysis

indeterminate hydrolysis

A solution of 0.0500 M HCl is used to titrate 27.0 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?

(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.)
