See lessThe main difference between an acid and a base is that
Polar/ionic solvents dissolve polar/ionic solutes and non-polar solvents dissolve non-polar solutes. For example, water is a polar solvent and it will dissolve salts and other polar molecules, but not non-polar molecules like oil.

See lessWeak acids generally have pKa
So weak acid may be used for preparing buffer solutions having pH values lying within the ranges pKa + 1 and pKa – 1. The acetic acid has a pKa of about 4.8. It may therefore be used for making buffer solutions with pH values lying roughly between the range 3.8 to 5.8.
