Characteristics and notes
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.
Safety and SDS
Read the safety data sheet before handling. Wear suitable gloves and eye protection.

Frequently asked questions
How is the chloride test done with potassium chromate?
Take 10 drops (or a measured volume) of sample, add 1 drop of 5% potassium chromate, then add 2.9% silver nitrate drop by drop with swirling until the colour changes permanently from yellow to red-brown; count the drops or read the burette.
How do I prepare 5% potassium chromate indicator?
Dissolve 5 g K2CrO4 in 100 ml distilled water; add silver nitrate dropwise until a faint red precipitate persists, let stand 12 h, filter — this removes chloride.
Is potassium chromate hazardous?
Yes — hexavalent chromium, toxic and carcinogenic; handle with gloves, avoid dust and dispose of as chromium waste.
