In science, potassium chromate is often used as an indicator, meaning it can identify the presence, location and quantity of certain elements such as iron. May cause genetic defects. Introduction. Add a small amount of K₂C rO₄ as indicator before starting determination, and then titrate with AgNO3 standard solution. Potassium Chromate, 5% (w/v), Chloride Free, Indicator for Argentometric Titrations. Swirl each flask gently to mix the contents. Potassium Chromate Indicator. Potassium chromate primarily affects the nose, throat and lungs causing ulcerations, shortness of breath, bronchitis, pneumonia and asthma but can also affect the gastrointestinal tract, liver, kidneys and immune system. The Mohr method uses chromate ions as an indicator in the titration of chloride ions with a May cause damage to organs (blood, kidneys, liver) through prolonged or … I. Potassium chromate can serve as an end point indicator for the argentometric determination of chloride, bromide and cyanide ions by reacting with silver ions to form a brick-red silver chromate precipitate in the equivalence point region. The quantitative estimation of the ions: chloride, bromide, and cyanide by titrating with a standard solution of silver-nitrate'>silver nitrate with a few millilitres of potassium chromate as an indicator form the basis of Mohr's method. Potassium chromate indicator method is a precipitation titration method that uses potassium chromate (K₂CrO₄) as indicator and silver nitrate (AgNO₃) as the standard solution.
