PH of solution during titration process
Q1: What is the pH of a 0.35 M solution of a weak acid HA with Ka = 1.41×10^-8?
Q2: A 25.0 mL sample of the acid is titrated against 1.9 M NaOH. What is the pH after 5.0 mL of the base has been added?
Q3: What is the pH after 10.0 mL of base has been added?
Q4: What is the pH when 30.0 mL of base have been added?
