The chemical formula of sodium hydroxide (not hydrate) is NaOH.
The formula name of a hydrate barium chloride and water is : BaCI2.2H2O
The formula corresponding to the name given is CuCl2. 4 H2O.
The experimental procedure for determining the formula for a hydrate that the formula for a hydrate is figured by the prefix and the number of water molecules that are in the compounds. For example is a prefix of di- and two water molecules. The formula is CaCl2 * 2H2O. The name for this is Calcium chloride dihydrate.
This formula is CaCl2.7 H2O
Anhydrate * X H2O
