Question

Potassium chlorate on heating gives potassium chloride and oxygen.

• A. True
• B. False

Answer 1

The correct option is A True

Decomposition of potassium chlorate -

• Potassium chlorate $\left({\mathrm{KClO}}_3\right)$ on heating in the presence of manganese dioxide $\left({\mathrm{MnO}}_2\right)$as a catalyst gives potassium chloride and oxygen.

$\underset{\mathrm{Potassium}\mathrm{chlorate}}{2{\mathrm{KClO}}_3\left(\mathrm{s}\right)}\underset{{\mathrm{MnO}}_2}{\overset{\mathrm{Heat}}{\to }}\underset{\mathrm{Potassium}\mathrm{chloride}}{2\mathrm{KCl}\left(\mathrm{s}\right)}+\underset{\mathrm{Oxygen}}{3{\mathrm{O}}_2\left(\mathrm{g}\right)}$

Therefore, the given statement is true.
