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 phosphate is another ionic solid that does not dissolve in water. This is also good because it is the material that bones and teeth are made of. Sodium carbonate breaks apart completely into ions that are incorporated throughout the water, forming a solution.oint out that the water molecules are attracted to the sodium and chloride ions of the salt crystal. Explain that the positive area of a water molecule is attracted to a negative chloride ion. The negative area water of a water molecule is attracted to a positive sodium ion.
