Problem- Calculate the volumes of 0.20M acetic acid, 0.20M sodium acetate, and pure water needed to make 20.00 mL of a buffer having pH=5.00. Repeat analogous, seperate calculations for buffers having pH=4.00 and pH=6.00. In each case determine the amounts of the acid and base that require the minimum volume of added water to reach a total volume of 20.00 mL.

Explain the each and every step in detail for help
