Silver Chromate Precipitation

概要

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.

日常の例

The Mohr titration is used to measure salt content in food, measuring chloride by adding silver nitrate until the red silver chromate endpoint appears.
