A 20.0 mL sample of hypobromous acid (HBrO) was titrated with 0.180 M KOH. To reach the equivalence point required 27.75 mL of KOH. Ka for HBrO is 2.8 x 10^-9
a) what is the initail pH of this solution of hypobromous acid?
b) what is the pH of the solution at the equivalence point?
c) what would the pH of the solution be after the addition of the first 10.00 mL of base?
d) What would be the pH after adding 30.0 mL of the base?
