what do you observe when pb(No3)2 undergoes heating.write it in the form of chemical reaction
Answers
Lead nitrate on heating decomposes to lead monoxide, nitrogen dioxide and oxygen.
2Pb(NO3)2 = 2PbO + 4NO2 + O2.
NO2 is liberated, along with oxygen, as a reddish brown gas. The residue left is lead monoxide.
Answer:
Heating decomposes lead nitrate into lead monoxide, nitrogen dioxide, and oxygen when Pb(NO₃)₂ undergoes heating.
Explanation:
Below is the chemical reaction that will take place:
2Pb(NO3)2 = 2PbO + 4NO2 + O2
As a result, NO2 is released as a reddish-brown gas together with oxygen. Lead monoxide is what's left.
Lead nitrate is a sand-like white or colorless substance. It's utilized in the manufacture of matches and specific explosives, as well as the dye and photographic industries, as well as process engraving. Lead nitrate is a crystalline white substance. The substance is water-soluble. Although it is noncombustible, it will hasten the combustion of combustible items.
Thus, heating causes lead nitrate to degrade, a feature that has been employed in pyrotechnics.
