Question

What happens when sodium nitrate is heated?

Answer 1

When we heat sodium nitrate(NaNO₃) then the products will be the sodium nitrite NaNO₂ and oxygen gas(O₂).

$2{\mathrm{NaNO}}_{3_{}}\stackrel{\mathrm{heat}}{\left(\mathrm{s}\right)\to }2{{\mathrm{NaNO}}_2}_{}\left(\mathrm{s}\right)+{\mathrm{O}}_{2_{}}\left(\mathrm{g}\right)$
