Sodium Dichromate 1Kg Loose Pack

Description

Sodium dichromate is an 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.[1] 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.

• Laboratory Reagent: Sodium dichromate is used as a reagent in laboratories for certain chemical tests.
• Industrial Applications: It has various industrial uses, including as a corrosion inhibitor, in the production of dyes and pigments, and in the tanning of leather.
• Wood Preservative: In the past, sodium dichromate was used as a wood preservative, but its use in this application has diminished due to environmental and health concerns related to chromium compounds.
