PH And Percent Ionization
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.
