Calcium Oxalate Precipitation (Kidney Stones)

CaCl2 + Na2C2O4 → CaC2O4↓ + 2NaCl

개요

Calcium chloride reacts with sodium oxalate to form a white precipitate of calcium oxalate (Ksp = 2.3 × 10⁻⁹). Calcium oxalate is the primary component of approximately 80% of kidney stones. The monohydrate form (whewellite) is thermodynamically favored and forms the hardest, most painful stones.
