About Sodium Dichromate 

Sodium dichromate is the inorganic compound with the formula Na2Cr2O7. Usually, however, the salt is handled as its dihydrate Na2Cr2O7·2H2O. Virtually all chromium ore is processed via conversion to sodium dichromate and virtually all compounds and materials based on chromium are prepared from this salt. In terms of reactivity and appearance, sodium dichromate and potassium dichromate are very similar. The sodium salt is, however, around twenty times more soluble in water than the potassium salt (49 g/L at 0 °C) and its equivalent weight is also lower, which is often desirable.

Sodium Dichromate Hazards

Sodium Dichromate may cause an asthma-like allergy. Future exposure can cause asthma attacks with shortness of breath, wheezing, coughing, and/or chest tightness. ulcers. Sodium Dichromate may damage the liver and kidneys.

Sodium Dichromate Used In Galvanizing

Sodium Dichromate is a chemical used as passivation. This chemical is used at the end of galvanizing process whereby it is used in quenching tank. Galvanized steel can form white rust whereby water (H2O) and zinc reacts quickly to form zinc hydroxide, a bulky white and relatively unstable oxide of zinc.
