Potassium Chromate Solution

Application:

Common laboratory chemical Potassium chromate is  strong oxidant. Suitability for chloride determination Indicator for volumetric chloride determination.

Using Procedure:

Place 10 drops of sample water in a test tube and add 1 drop of 5% potassium chromate (K2CrO4) solution as indicator. Add dropwise 2.9% silver nitrate with the same dropper until a permanent and distinct col.

Unlike the less expensive sodium salt, potassium salt is mainly used for laboratory work in situations where an anhydrous salt is required. It is as an oxidizing agent in organic synthesis. It is used as in.

Unlike the less expensive sodium salt, potassium salt is mainly used for laboratory work in situations where an anhydrous salt is required. It is as an oxidizing agent in organic synthesis. It is used as in qualitative inorganic analysis, e.g. as a colorimetric test for silver ion. It is also used as an indicator in precipitation titrations with silver nitrate and sodium chloride (they can be used as standard as well as titrant for each other) as potassium chromate turns red in the presence of excess of silver ions.
