Problem- 1. What is the pH of the solution obtained by mixing 50.00 mL of 0.1250 M HOAc and 25.00 mL of 0.1000 M NaOH?
2. Calculate the pH of a solution prepared by mixing 10.0 mL of 0.500 M NaOH and 20.0 mL of 0.50 M benzoic acid solution. (Benzoic acid is monoprotic; its ionization constant is 6.7 x 10^-5).
3. If Ka is 1. 85 x 10^-5 for acetic acid, calculate the pH at one-half the equivalence point and at the equivalence point for a titration of 50 mL of 0.100M acetic acid with 0.100 M NaOH. ( Hint hydrolysis is possible).
Demonstrate all steps to describe the solution of above question
