What happens when zinc granules are treated with dilute solutions of $NaCl$ and $NaOH$? Also,write the chemical equations if a reaction occurs.
(N/A) The reaction of $Zn$ granules with:
$(a)$ $NaCl$ solution:
$Zn(s) + NaCl(aq) \rightarrow$ No reaction.
Zinc is less reactive than sodium,so it cannot displace sodium from its salt solution.
$(b)$ $NaOH$ solution:
$Zn(s) + 2NaOH(aq) \rightarrow Na_2ZnO_2(aq) + H_2(g)$
When zinc reacts with a hot concentrated solution of sodium hydroxide,it forms sodium zincate and releases hydrogen gas.
