    Used as analytical reagent, oxidant, mordant and metal rust inhibitor;used for the manufacture of chromate,used as oxidant and mordant of printing and dyeing.    

    Used for ink, paint, enamel, metal corrosion and so on,mainly used in the manufacture of chemical reagents and pigments.
    Potassium chromate (K2CrO4) is soluble in water and is used to make bright yellow inks and paint pigments.   It is also used as a reagent in chemical laboratories and as a mordant to “fix” dyes in colored textiles.
    It is used as an oxidizing agent.
    Has a limited application in enamels, finishing leather, rustproofing of metals, being replaced by the sodium salt;  as reagent in analytical chemistry.
