sodium chromate

When ammonia does not return to the boiler, the sodium chromate is destroyed by excess heat.

It is a common laboratory chemical, whereas sodium chromate is important industrially.

Alternatively, it can be created by the interaction of barium chloride with sodium chromate.

Sodium chromate, like other hexavalent chromium compounds, is toxic and carcinogenic.

Sodium chromate is the inorganic compound with the formula NaCrO.

The sodium chromate is reacted with sulfuric acid to produce sodium dichromate.

It is normally made by reacting sodium chromate or potassium chromate with sulfuric acid.

The industrial route to chromium(III) oxide involves reduction of sodium chromate with sulfur.

Sodium chromate is a chemical compound composed of sodium ions and chromate ions.

Once the sodium chromate is destroyed intergranular corrosion which leads to stress corrosion cracking will eventually result in a cooling unit rupture.

Sodium chromate is produced industrially by the oxidative roasting of chromite ore with calcium or sodium carbonate.

It is heated with sodium carbonate to make sodium chromate, iron(III) oxide, and carbon dioxide.

Chromium trioxide is generated by treating sodium chromate or the corresponding sodium dichromate with sulfuric acid:

Aside from its central role in the production of chromium from its ores, sodium chromate is used as a corrosion inhibitor in the petroleum industry.

In organic chemistry, sodium chromate is used as an oxidant, converting primary alcohols to carboxylic acids and secondary alcohols to ketones.

Sodium chromate (5 1 Cr)(Amersham International) was added dropwise to the pellet, with continuous mixing, to a final activity of 55.5 kBq/kg body weight.

Strontium chromate is prepared from the reaction of strontium chloride with sodium chromate, or from a reaction between strontium carbonate with sodium dichromate.

Although a number of the drilling mud samples had relatively high amounts of chromium due to the addition of sodium chromate, there was a low correlation between chromium concentration and toxicity.

Formerly, sodium sulfate was also a by-product of the manufacture of sodium dichromate, where sulfuric acid is added to sodium chromate solution forming sodium dichromate, or subsequently chromic acid.

Chromium(VI) peroxide (CrO) or chromium oxide peroxide is an unstable compound formed by the addition of acidified hydrogen peroxide solutions to solutions of metal chromates, such as sodium chromate.
