Zinc Hydroxide as Amphoteric Base with HCl

Zn(OH)2 + 2HCl → ZnCl2 + 2H2O

Übersicht

Zinc hydroxide, like aluminum hydroxide, is amphoteric and dissolves in hydrochloric acid to form zinc chloride and water. The white gelatinous precipitate dissolves as the Zn²⁺ ions form. This behavior is used in qualitative analysis to distinguish zinc from non-amphoteric metal hydroxides.
