Innovating Science® - Ampholytes Demonstration

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