The chemical formula of calcium hydrogen carbonate is Ca(HCO3)2; this compound (which contain calcium, carbon and hydrogen) exist only in water solution.
When one compound dissolves into another compound, it becomes a solution.

Sodium dihydrogen carbonate is not a proper chemical name and therefore has no formula, because carbonate anions have only two negative charges and therefore can not form a neutral compound with one sodium atom and two hydrogen atoms. The closest analogous compound is sodium hydrogen carbonate, which has the formula NaHCO3.
