1. Determine the pH and the percent ionization in a 0.50M solution of KOBr.
The Ka for HOBr = 2.5 x 10 ^ -9.

2. Calculate the number of grams of KOBr that must be added to 1.5L of 0.200M HOBr to prepare a buffer solution of pH 8.50.

Assume no change in volume. The Ka for HOBr = 2.5 x 10^-9.

1.
KOBr ---> K+ + BrO-

BrO- + H2O ---> HOBr + HO-

Kb = Kw/Ka = 10^-14 / (2.5 x 10^-9) = 4 x 10^-6 = [HO-][HOBr] / [BrO-] = x^2 / (0.5 - ...
