    Zinc hydroxide - Wikipedia

    Zn(OH) 2 + 2 OH − → Zn(OH) 4 2−. This property can be used as a test for zinc ions in solution, but it is not exclusive, since aluminum and lead compounds behave in a very similar manner. Unlike the hydroxides of aluminum and lead, zinc hydroxide also dissolves in excess aqueous ammonia to form a colorless, water-soluble ammine complex.
