Sodium dichromate is an inorganic compound with the chemical formula Na2Cr2O7. Usually, 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 is an odorless, red or red-orange, crystalline (sand-like) solid inorganic chemical. It is used as a corrosion inhibitor and to make other chemicals. It is very soluble in water.
