Calcium acetate is a chemical compound which is a calcium salt of acetic acid. It has the formula Ca(C 2 H 3 O 2) 2. Its standard name is calcium acetate, while calcium ethanoate is the systematic name. An older name is acetate of lime. The anhydrous form is very hygroscopic; therefore the monohydrate (Ca(CH 3 COO) 2 •H 2 O) is the common form.

According to the Nickel–Strunz classification, calclacite is an organic acid salt and occurs with formicaite (calcium formate), acetamide, dashkovaite (magnesium acetate), paceite (calcium copper acetate) and hoganite (copper acetate). [2] It is white and its hardness on the Mohs scale is 1.5.
Calcium acetate and magnesium carbonate compounds bind phosphorus derived from food thereby forming indigestible phosphate salts in the intestine that are subsequently excreted with the faeces. The aim of the therapy is to reach a normal serum phosphorus level, i.e. between 0.81 and 1.45 mmol/L (2.5–4.5 mg/dL).
An acetate is a salt formed by the combination of acetic acid with a base (e.g. alkaline, earthy, metallic, nonmetallic or radical base). "Acetate" also describes the conjugate base or ion (specifically, the negatively charged ion called an anion) typically found in aqueous solution and written with the chemical formula C 2 H 3 O − 2.
The reaction of calcium carbide with water, producing acetylene and calcium hydroxide, [5] was discovered by Friedrich Wöhler in 1862. CaC 2 ( s ) + 2H 2 O ( l ) → C 2 H 2 ( g ) + Ca(OH) 2 (aq) This reaction was the basis of the industrial manufacture of acetylene , and is the major industrial use of calcium carbide.
Calcium sulfite is used as a bleach in papermaking and as a disinfectant, calcium silicate is used as a reinforcing agent in rubber, and calcium acetate is a component of liming rosin and is used to make metallic soaps and synthetic resins. [47] Calcium is on the World Health Organization's List of Essential Medicines. [53]
Calcium oxalate is a combination of calcium ions and the conjugate base of oxalic acid, the oxalate anion. Its aqueous solutions are slightly basic because of the basicity of the oxalate ion. The basicity of calcium oxalate is weaker than that of sodium oxalate, due to its lower solubility in water.
