Calcium acetate is an acetate of calcium that has a distinctive odor of white to brown or gray crystals. The common name for calcium acetate is calcium acetate. Anhydrous calcium acetate is very hygroscopic, so common calcium acetate exists in the form of monohydrate (Ca(CH3COO)2.H2O.
If alcohol is added to a saturated calcium acetate solution, a semi-solid, flammable colloid is formed, much like a canned fuel product, such as Sterno. California Snowball is a combination of calcium acetate and ethanol. The resulting colloid is white in color and piles up like a snowball.
Chlorocalcin acetate is calcium acetate chloride pentahydrate, which is considered a mineral but is often produced by human activities.
use
In kidney disease, the concentration of phosphoric acid in the blood may be elevated (hyperphosphate blood) and cause some bone problems. Calcium acetate can be taken in the diet to bind excess phosphoric acid. The side effect of this method is a stomachache.
Calcium acetate is also a food additive, mainly used in confectionery products.
preparation
CaCO3(s) + 2CH3COOH(aq) → Ca(CH3COO)2(aq) + H2O(l) + CO2(g)
Ca(OH)2(s) + 2CH3COOH(aq) → Ca(CH3COO)2(aq) + 2H2O(l)
Exposure and health effects
Contact route
The substance can be absorbed into the body by inhalation and ingestion.
Effects of short-term exposure
The substance irritates the eyes, skin and respiratory tract.
Inhalation hazard
The diffusion quickly reaches the concentration of particulate matter pollution in the air.
Effects of prolonged or repeated exposure
