Question

Write the equation to represent the reaction of Sodium hydroxide (i) with zinc metal

Answer 1

1. Chemical equation:

A chemical equation is a representation of a chemical reaction with the reactants on the left and the products on the right, both separated by an arrow.

2. Reaction of Sodium hydroxide with Zinc metal

Sodium hydroxide is a very strong base with the molecular formula NaOH. The reaction of Sodium hydroxide (base) with Zinc (metal) yields a salt named Sodium zincate and Hydrogen gas.
The chemical equation for the reaction of Sodium hydroxide with Zinc metal is given below.

$$\begin{gathered} \mathrm{Zn}\left(\mathrm{s}\right)+2\mathrm{NaOH}\left(\mathrm{aq}\right)\to {\mathrm{Na}}_2{\mathrm{ZnO}}_2\left(\mathrm{aq}\right)+{\mathrm{H}}_2\left(\mathrm{g}\right) \\ \mathrm{Zinc}\mathrm{Sodium}\mathrm{Sodium}\mathrm{zincate}\mathrm{Hydrogen} \\ \mathrm{hydroxide} \end{gathered}$$
