Question

What is the color of lead nitrate before heating?

Answer 1

Color of Lead nitrate

• The chemical formula of Lead nitrate is $\mathrm{Pb}{\left({\mathrm{NO}}_3\right)}_2$.
• The color of lead nitrate is white before heating.
• On heating Lead nitrate, the formation of Lead oxide (Yellow in colour), Nitrogen dioxide and oxygen takes place.
• The reaction is as follows:-
• $2\mathrm{Pb}{\left({\mathrm{NO}}_3\right)}_2\left(\mathrm{s}\right)\stackrel{∆}{\to }2\mathrm{PbO}\left(\mathrm{s}\right)+4{\mathrm{NO}}_2\left(\mathrm{l}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)$
