a) A buffer solution contains 0.292 M CH3NH3Br and 0.447 M CH3NH2 (methylamine). Determine the pH change when 0.098 mol HCl is added to 1.00 L of the buffer.
pH after addition - pH before addition = pH change = ________
b) Determine the pH change when 0.104 mol HNO3 is added to 1.00 L of a buffer solution that is 0.386 M in CH3COOH and 0.372 M in CH3COO-.________
