12 Question (2 points) Zn(ll) hydroxide is amphoteric (amphiprotic). Complete and balance the following equations. 2nd attempt Part 1 (1 point) Feedback Include the phases of all species in the chemical equations. Complete and balance a chemical equation showing how an aqueous suspension of this con acid. X X Ho - (aq). . Zn(OH),(s) + 2H(aq) Zn²+ (aq) + 21,0(1)

Answer 1

here when strong base is added it forms the complex with different moles of OH- they are as follows

if one moles of OH^- is added then the equation is as follows

Zn(OH)₂ (s) + OH^- (aq) -------------------------> [ Zn(OH)₃]^2- (aq)

if two moles of OH^- is added then the equation is as follows

Zn(OH)₂ (s) + 2 OH^- (aq) -------------------------> [ Zn(OH)₄]^2- (aq)

here it is strong base so it takes 2 moles of OH- and forms the complex

Zn(OH)₂ (s) + 2 OH^- (aq) -------------------------> [ Zn(OH)₄]^2- (aq) ( be sure about indicating the phases of reactants and products )
