Similar to acetic acid, benzoic acid is a weak acid (HA) and is a commonly used as antimicrobial preservative in food and beverages, especially in carbonated beverages Suppose 10.00-mL of 0.5000 M benzoic acid (C6H5COOH) is titrated with 0.2000M NaOH. Ka for benzoic acid is 6.3 x 10-5 . What is the pH after addition of 35.00 mL of NaOH to the benzoic acid solution?

Which of the following aqueous mixtures will result in a buffer with a pH higher than 7.0? (For HCNO, Ka = 2.2×10-4, for NH3, Kb = 1.8×10-5 ) 10 mL of 0.1 M NH3 + 10 mL of 0.1 M HCl   10 mL of 0.1 M HCNO + 5.0 mL of 0.1 M NaOH   10 mL of 0.1 M HCNO + 10 mL of 0.1 M NaOH   10 mL of 0.1 M NH3 + 5.0 mL of 0.1 M HCl   10 mL of 0.1 M NH3 + 10 mL of 0.1 M HCNO

Determine the pH at the point in the titration of 40.0 mL of 0.200 M H,NNH2 with 0.100 M HNO, after 80.0 mL of the strong acid has been added. The value of Kb for H,NNH, is 3.0 x 10-6.
