Question

Zn(II) hydroxide is amphoteric. Complete and balance a chemical equation showing how an aqueous suspension of this compound reacts to the addition of a strong acid. Include the phases of all species in the chemical equation. Complete and balance a chemical equation showing how an aqueous suspension of this compound reacts to the addition of a strong base. Injclude phases. OH (aq. Zn OH Tip: Plus signs can be typed from the keyboard. Include phases in the balanced chemical equation. Click on the (aq) button in the tools to select the phase to add. Phases should not be subscripted

Explanation / Answer

Zn(OH)2 is highly soluble in strong acid

The reaction of Zn(OH)2 with strong acid is

Zn(OH)2(s)+ 2H+ (aq) ------> Zn+2 (aq)+ 2H2O

The reaction of Zn(OH)2 with strong base is

Zn(OH)2 (s) + 2OH- (aq) -----> Zn(OH)4-2 (aq)
