Question
Which two sets of reactants best represent the amphoteric character of Zn(OH)2?<br>Set 1 : Zn(OH)2(s) and OH^-(aq)<br>Set 2 : Zn(OH)2(s) and H2O(l)<br>Set 3 : Zn(OH)2(s) and H^+(aq)<br>Set 4 : Zn(OH)2(s) and NH3(aq)
Answer: B
💡 Solution & Explanation
(b) Zn(OH)2(Acid) + 2OH^-(Base) $\rightarrow$ ZnO2^2-(Salt) + 2H2O(Water)<br>Zn(OH)2(Base) + 2H^+(Acid) $\rightarrow$ Zn^2+(Salt) + 2H2O(Water)
