Calcium Phosphate Precipitation (Bone Mineral)
3CaCl2 + 2Na3PO4 → Ca3(PO4)2↓ + 6NaCl
Tổng quan
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.

Ví dụ thực tế
Your bones and teeth are built from a form of calcium phosphate. Maintaining adequate calcium and phosphorus intake keeps this mineral being deposited.
Tầm quan trọng công nghiệp
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.
