Sodium Dichromate

Sodium Dichromate is an orange to red-colored, crystalline, inorganic compound, with a formula Na₂Cr₂O₇, that emits toxic chromium fumes upon heating. Sodium dichromate is highly corrosive and is a strong oxidizing agent. This substance is mainly used to produce other chromium compounds but is also used in drilling muds, in metal treatments, in wood preservatives, in the production of dyes and organic chemicals and as a corrosion inhibitor.

Sodium dichromate primarily affects the respiratory system causing ulcerations, shortness of breath, bronchitis, pneumonia, and asthma but can also affect the gastrointestinal tract, liver, kidneys and immune system. This substance is a known human carcinogen and is associated with an increased risk of developing lung cancer and cancer of the sinonasal cavity.

Applications of Sodium bisulfate

Apart from its importance in the production of other chromium products, sodium dichromate also has uses as an ingredient in the production of the following:

Metallic finish:
It helps prevent corrosion, makes it easier to clean metallic surfaces, and allows for paint to stick.

Organic products:
Used as oxidizers in the production of vitamin K and wax.

Pigments:
Used to make inorganic chromate pigments where it produces a range of light-stable colors. Some grades of chromate are used to prevent corrosion in undercoats and primers.

Ceramics:
Used in the production of colored glass and ceramic glaze.

Textiles:
Used as a mordant for acidic dyes to improve color-fast properties.
