Question

When sodium is oxidized it forms_______

Answer 1

When Sodium$\left(\mathrm{Na}\right)$ is oxidized it forms Sodium peroxides.

• Sodium is a group $1$highly reactive metals., that belongs to $\mathrm{s}-$block element.
• When sodium ignites spontaneously when exposed to air, Sodium on oxidation gives sodium peroxides.

$2\mathrm{Na}\left(\mathrm{s}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)\to {\mathrm{Na}}_2{\mathrm{O}}_2\left(\mathrm{s}\right)$

• When sodium undergoes a reaction in the free supply of air gives sodium oxide as a minor product and sodium peroxides as a major product.

$4\mathrm{Na}\left(\mathrm{s}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)\to 2{\mathrm{Na}}_2\mathrm{O}\left(\mathrm{s}\right)$

Therefore, sodium on oxidation gives sodium peroxides.
