Sodium carbonate is the salt of weak acid carbonic acid with strong base sodium hydroxide. Carbonic acid is dibasic acid. Sodium carbonate contains sodium cations and carbonate anions. Sodium cation has unit positive charge and can be represented as Na+
. Carbonate anion has two negative charges and can be represented as CO2−3
. The formula of sodium carbonate can be obtained by applying the criss cross method.
The charge on sodium cation is +1. Hence, the number of carbonate ions will be one. The charge on carbonate ions is -2. Hence, there will be two sodium cations.
The molecular formula of sodium carbonate is Na2CO3
