Calcium Oxalate Precipitation (Kidney Stones)

CaCl₂ + Na₂C₂O₄ → CaC₂O₄↓ + 2NaCl

Descripción general

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.

Ejemplo cotidiano

Most kidney stones are calcium oxalate crystals. Foods high in oxalate (spinach, rhubarb, almonds) can increase stone risk.

Importancia industrial

Comprender la precipitación del oxalato de calcio es crítico en nefrología, ciencia de los alimentos (análisis del contenido de oxalato) y en la elaboración de cerveza (prevención de la piedra de cerveza).
