Ampholytes are compounds which react with both acids and bases. When zinc chloride is reacted with sodium hydroxide the soluble zincate ion is formed.

In this experiment, you will prepare three buffer solutions having different pH values and show that the pH of these solutions does not change significantly when small amounts of acids and bases are added. You will also show that when the same
