Sodium carbonate is:

An aqueous solution of sodium carbonate gives alkaline tests . Why ?

Fusion of chromite ore with sodium carbonate in excess of air gives a compound (X) (yellow solution) X when treated with sulphuric acid gives:

One among the following compounds will not give effevesecence with sodium carbonate :

An aqueous solution of sodium carbonate is alkaline because sodium carbonate is a salt of
