Calcium acetate is a mineral chemical compound that usually contains 1 crystallization water (because dry calcium acetate is highly dehumidifying and rapidly converts to a monohydrate state). Calcium acetate is produced by the reaction of calcium salts with acetic acid.
CaCO2 + 2CH3COOH → Ca(CH3COO)2 + H2O + CO2
Ca(OH)2 + 2CH3COOH → Ca(CH3COO)2 + 2H2O
Calcium acetate can be made from a combination of water and vinegar with calcium carbonate (found in eggshells or carbonate rocks such as limestone and marble) or calcium hydroxide.
In kidney disease, the amount of blood phosphate (hyperphosphatemia, which causes bone problems) may increase; Therefore, calcium acetate binds to phosphate and reduces the amount of phosphate in the blood.
Calcium acetate was used as an oral additive, especially in the candy industry as stabilizer and buffer.
Chemistry teachers usually prepare white snowballs for students in laboratories by combining calcium acetate solution with ethanol. This gel is known because it looks like a snowball.
