The molecular formula of Sodium carbonate is Na2CO3, consisting of two sodium ions (Na+) and one carbonate ion (CO32-). The molecular weight refers to the sum of the relative atomic masses of all atoms in a molecule, expressed in g/mol. The molecular weight of Sodium carbonate can be d...
Baking soda is pure sodium bicarbonate. The molecular formula for sodium bicarbonate is NaHCO3. An interesting reaction is created, by the way, when youmix baking soda and vinegar. The two chemicals combine to generate carbon dioxide gas, which you can use for experiments such aschemicalvolcanoes...
