What is the main chemical constituent of bone ash used in various chemical and agricultural applications?

💡 Solution & Explanation

Bone ash consists primarily of calcium phosphate, specifically tricalcium phosphate, which is derived from the calcination of animal bones. Other alternatives like calcium carbonate form limestone rather than skeletal remains, while calcium chloride and sulfate serve different industrial purposes. Bone ash serves as an essential raw material in the manufacturing of bone china and metallurgical refining.
