With the same initial solution of 0.75 moles formate and 0.85 moles formic acid to make a buffer solution. The Ka of formic acid is 1.8x10-4.

You add 60.7g hydrobromic acid to this solution, what is the new pH?

Solutions

Expert Solution

moles of HBr added = mass / molar mass = 60.7 g / 80.91 = 0.750 mol HBr
