Question- Part 1) 15 ml of 3.0 M NaOH are added to the following-

- 500.0 ml of pure water

- 500.0 ml of 0.1 M formic acid

- 500.0 ml of 0.1 M formate of potassium

- 500.0 ml of a solution containing 0.1 M formic acid and 0.1 M formate of potassium.

Calculate the difference of pH resulting from the addition in all four cases.

Part 2) What would be the difference of pH after addition of 20.0 ml of NaOH to 500.0 ml of a solution containing 0.1 M formic acid and 0.1 M formate of potassium?

I need help for above question. Show each steps for the above problem.
