A compound, Y of sodium forms a white powder. It is a constituent of baking powder and isused in some antacids. When heated it gives a compound, Y which is anhydrous and absorbs water to become hydrated salt. When this salt is kept in open air, it loses water molecules in a process
called efflorescence. When dissolved in water it forms a strong base and a weak acid, Z.
Identify the compound, Z
