DATA ANALYSIS 3. Some salts, when they form, may trap water are referred to as hydrated salts. The structure. This is referred to as an anhydrous sait. of water molecules per unit of salt (e.g. xg H, per When heated, the water can be drivent from the salt it results in the anhydrous form of that sa chloride. In its anhydrous form the formula for form the formula for cobalt chloride is CoCl2 XH2O per given unit of salt. If...
