What is Sodium Dichromate?
Sodium dichromate is an inorganic compound with the formula Na2Cr2O7. It is a salt consisting of sodium ions and dichromate ions. Sodium Dichromate is a orange-red solid that is soluble in water. It is used in dyeing and leather tanning.
Sodium Dichromate Structure
Sodium Dichromate is a compound made up of sodium, chromium and oxygen atoms. The sodium atom is the largest, followed by the chromium atom, and then the oxygen atom. The compound is held together by covalent bonds. The chromium atom has a +3 oxidation state, and the oxygen atom has a -2 oxidation state.
Production of Sodium Dichromate
Sodium dichromate is an inorganic compound with the formula Na2Cr2O7. It is a yellow-orange solid that is very soluble in water. It is a salt of chromium(VI) and sodium.
Sodium dichromate is produced by the reaction of sodium carbonate and chromic acid:
2Na2CO3 + Cr2(SO4)3 → 2Na2Cr2O7 + CO2
The chromic acid can be obtained by the oxidation of chromium metal with concentrated sulfuric acid:
2Cr + 3H2SO4 → 2Cr2(SO4)3 + 3H2O
Sodium Dichromate Uses
Sodium dichromate is used as a chromium ore, as a textile dye, and in the production of chromium salts. It is also used as a corrosion inhibitor and in the manufacture of dyes and pigments.
Health Hazards of Sodium Dichromate
Sodium dichromate is a corrosive and toxic chemical. It can cause skin and eye irritation, respiratory problems, and even death if ingested in high doses.
