Amphoteric Hydroxide - GOR-72715H

Chemistry experiment , Reaction of an Amphoteric Hydroxide. Initially all three beakers contained a suspension of chromium (III) hydroxide, Cr(0H)3. The middle beaker remains untreated. The hydroxide on the left was dissolved by adding concentrated HCI(aq) to form violet-colore Cr3+(aq). The hydroxide on the right was dissolved by adding concentrated Na0H to form green Cr(0H)4-(aq).
