What is PbCO3? Important knowledge about PbCO3.

  1. Definition of PbCO3
    PbCO3, also known as plumb spar, is an inorganic chemical substance with the molecular formula PbCO3. It consists of one lead atom (Pb), one carbon atom (C), and three oxygen atoms (O). PbCO3 has a molecular weight of 267.2 g/mol.

  2. Properties: PbCO3
    PbCO3 is a solid, crystalline substance that is colorless or white. It has an unclear smell. PbCO3 does not dissolve or dissolves very little in water, but it does dissolve in acid. When diluted in water, the pH of the solution does not change, therefore PbCO3 is a neutral substance. PbCO3 decomposes when heated into PbO and CO2.

  3. Common chemical equations of PbCO3
    3.1 Metal reaction:
    PbCO3 does not directly react with metals.
    3.2 Acid reaction: PbCO3 can react with strong acid to form salt and CO2 gas. For example:
    PbCO3 + 2HCl -> PbCl2 + H2O + CO2
    PbCO3 + H2SO4 -> PbSO4 + H2O + CO2
    3.4 Non-metal reaction: PbCO3 does not directly react with non-metals.

  4. Preparation of PbCO3
    4.1 Laboratory preparation of PbCO3:
    PbCO3 can be prepared by reacting Pb(NO3)2 with Na2CO3 or (NH4)2CO3 in a water solution. For example: Pb(NO3)2 + Na2CO3 -> PbCO3 + 2NaNO3
    4.2 Industrial preparation of PbCO3:
    In industry, PbCO3 is produced by reacting PbO with CO2.
