Question

State whether the following statements are “true” or “false”.

Red lead oxide on strong heating gives off oxygen gas.

• A. True
• B. False

Answer 1

The correct option is A True

• Red lead oxide (${\mathrm{Pb}}_3{\mathrm{O}}_4$) upon strong heating results in the formation of Lead oxide($\mathrm{PbO}$) which is reddish-brown in color and Oxygen gas (${\mathrm{O}}_2$)
• ${\mathrm{Pb}}_3{\mathrm{O}}_4$ is called red lead oxide as it is red in color
• $\underset{\mathrm{Red}\mathrm{lead}\mathrm{oxide}}{2{\mathrm{Pb}}_3{\mathrm{O}}_4\left(\mathrm{s}\right)}\stackrel{490°\mathrm{C}}{\to }\underset{\mathrm{Lead}\mathrm{Oxide}}{6\mathrm{PbO}\left(\mathrm{s}\right)}+\underset{\mathrm{Oxygen}}{{\mathrm{O}}_2\left(\mathrm{g}\right)}$

Hence, the given statement is true.
