Calcium acetate hydrate is a white, crystalline compound derived from calcium acetate, commonly used in food, medicine, and laboratory applications where a calcium source or buffering agent is needed.
🏭⚗️ Production
Calcium acetate hydrate is produced by the reaction of calcium carbonate or calcium hydroxide with acetic acid. The resulting calcium acetate can then crystallize with water molecules to form the hydrate under controlled cooling and evaporation conditions.
🔬 Properties
Calcium acetate hydrate appears as a white, odorless, hygroscopic crystalline solid. Its chemical formula is typically written as Ca(C₂H₃O₂)₂·xH₂O, where x depends on the degree of hydration. It has a molar mass of approximately 158.17 g/mol (anhydrous form), is highly soluble in water, and has a mild vinegar-like taste due to the acetate ion.
🧪 Applications
Calcium acetate hydrate is used as a phosphate binder in patients with kidney disease, as a food additive (E263) to preserve and stabilize products, and in chemical laboratories as a source of calcium ions. It also plays a role in the preparation of other calcium compounds.
⚠️ Safety
Calcium acetate hydrate is generally regarded as safe when used in appropriate amounts, especially in food and pharmaceutical contexts. However, excessive ingestion may cause gastrointestinal discomfort. Proper storage in a dry, sealed container is recommended, as the compound is hygroscopic and may absorb moisture from the air.
