Calcium Phosphate Precipitation (Bone Mineral)

3CaCl₂ + 2Na₃PO₄ → Ca₃(PO₄)₂↓ + 6NaCl

Ikhtisar

Calcium chloride reacts with trisodium phosphate to form a white precipitate of calcium phosphate (Ksp = 2.1 × 10⁻³³). Calcium phosphate, particularly the hydroxyapatite form Ca₅(PO₄)₃OH, is the primary mineral component of bones and teeth. It accounts for about 70% of bone mass.

Contoh Sehari-hari

Your bones and teeth are built from a form of calcium phosphate. Maintaining adequate calcium and phosphorus intake keeps this mineral being deposited.

Pentingnya dalam Industri

Calcium phosphate is used in bone grafts and dental implants, as a food supplement, in ceramics, and as the raw material for phosphoric acid production.
