크로뮴산은 침전

2AgNO3 + K2CrO4 → Ag2CrO4↓ + 2KNO3

개요

Silver nitrate reacts with potassium chromate to form a brick-red precipitate of silver chromate (Ksp = 1.1 × 10⁻¹²). This reaction is the basis of the Mohr method for determining chloride concentration by titration with AgNO₃ using K₂CrO₄ indicator.
