Assertion : The decahydrated form of sodium carbonate on standing in air effloresces.
Reason : It converts into monohydrate having formul, `Na_(2)CO_(3).H_(2)O`.

This question has Statement I and Statement II. Of the four choices given after the Statements, choose the one that best describes the two Statements. Statement - I : The decahydrated form of sodium carbonate on standing in air effloresces. Statement - II : It converts into monohydrate having formula, Na_2CO_3.H_2O.

Na_(2) CO_(3). 10 H_(2) O is

The formula of sodium carbonate is Na_(2)CO_(3) .
