Sodium Carbonate - an overview ScienceDirect Topics

2010-10-3  Sodium carbonate commonly occurs as a crystalline decahydrate (Na 2 CO 3 10H 2 O), which readily effloresces to form a white powder, the monohydrate (Na 2 CO 3 H 2 O). Pure sodium carbonate is a white, odorless powder that is hygroscopic (absorbs moisture from the air) and that forms a moderately basic solution in water.
