Question

Consider the given chemical reaction

$2NaOH+Zn\to$

The products of the above reaction are

• A. $N{a}_{2}O,ZnOand{H}_2$
• B. $N{a}_{2}Zn{O}_{2}and{H}_2$
• C. $Zn(OH{)}_{2}andN{a}_{2}O$
• D. $N{a}_{2}Zn{O}_{2}and{H}_{2}O$

Answer 1

The correct option is B $N{a}_{2}Zn{O}_{2}and{H}_2$

Metals react with bases to form salt and evolve hydrogen gas.

$\underset{\left(\mathrm{Sodium}\mathrm{hydroxide}\right)}{2\mathrm{NaOH}}+\underset{\left(\mathrm{Zinc}\right)}{\mathrm{Zn}}\to \underset{\left(\mathrm{Sodium}\mathrm{zincate}\right)}{{\mathrm{Na}}_2{\mathrm{ZnO}}_2}+\underset{\left(\mathrm{Hydrogen}\mathrm{gas}\right)}{H_2\uparrow }$
Hence, the correct answer is option (b).
