Bichromate sodium

Sodium dichromate (sodium dichromate, sodium the bichromate) is an inorganic chemical compound, sodium salt dichromic acid.

The intermediate in the production of chromium, virtually all chromium ore is processed in dichromate sodium.

You should consider the sodium dichromate is very toxic.

From the point of view reactivity and appearance, sodium dichromate and potassium dichromate are very similar. The sodium salt, however, twenty times more soluble in water than the potassium salt (49 g/l at 0 °C) and its equivalent mass is also smaller — so it is the most frequently used substance.

Similarity chrome acid and dichromate of sodium is a common property — they are strong oxidizing agents. In relation to the potassium salt, the main advantage of sodium dichromate is its greater solubility in water and in polar solvents, such as acetic acid.

Applies to:
- In the leather and fur industry for tanning leather and fur;
- In the chemical industry in the manufacture of inorganic pigments catalysts and other chromium-containing compounds;
- In textile industry for dyeing of fabrics as mordants;
- In some other industries in the composition piscivorous mixtures, antifreeze for engines, acetylene, purification and chemical reagents.

The sodium dichromate is Packed in steel drums for chemical products, plastic liner bags, nested in four-, five-layer paper bags or flax-goto-kanatnyi bags or jute bags.
Bichromate of sodium transporterowych all kinds transport in covered vehicles. By rail Packed products transporterowych carload shipments. Soft specialized containers transporterowych open rolling stock without overloading the path route. The shelf life of the product limited.
