Calcium Phosphate Precipitation (Bone Mineral)

3CaCl2 + 2Na3PO4 → Ca3(PO4)2↓ + 6NaCl

개요

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.
