A Correct answer
Explanation

The chemical compound calcium acetate is the calcium salt of acetic acid. It has the formula Ca(C2H3O2)2. In kidney disease, blood levels of phosphate may rise (called hyperphosphatemia) leading to bone problems. Calcium acetate binds phosphate in the diet to lower blood phosphate levels. Calcium acetate is used as a food additive, as a stabilizer, buffer and sequestrant, mainly in candy products.
