Sodium Carbonate. Sodium carbonate is a sodium salt of carbonic acid and a strong base. It is supplied as a white, odorless powder that is hygroscopic and very soluble in water producing a strong alkaline solution.
Calcium carbonate, in nature, also commonly dissolves. It's just not as immediate as dissolution of the more soluble ionic compounds. You are probably familiar with this phenomenon: This forms because calcium carbonate dissolves. The rock is limestone, which is usually composed of pure calcium carbonate.Acidic water greatly enhances the solubility of calcium carbonate, and it doesn't even need to be highly acidic.o note that solubility of ionic compounds are not absolute. In fact, solubility in water is often given as a value in g/L of water. However, generally, we define solubility as: 1  Soluble substances can form a 0.1M solution at 25 Â°C. 2  Insoluble substances cannot form a 0.1M solution at 25 Â°C.
