Calcium Acetate is the calcium salt of acetic acid. It has the formula Ca(C2H3OO)2. Its standard name is calcium acetate, while calcium ethanoate is the systematic IUPAC name. An older name is acetate of lime. The anhydrous form is very hygroscopic; therefore the monohydrate (Ca(CH3COO)2•H2O is the common form.
