A) What is the pH of a KAc/HAc buffer if the salt concentration is 60% higher than that of the acid?
B) Equal volumes of two strong acids are mixed. The pH of one is 3.80. The pH of the other is 4.80. What is the pH of the mixture?
C) 20.00 mL of 0.100 M HCl plus 10.00 mL of 0.100 M NaOH. What is the pH?
