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. It is also a dyeing auxiliary in the textile industry. It is a diagnostic pharmaceutical in determining red blood cell volume.<\/p>\n
In organic chemistry, sodium chromate is used as an oxidant, converting primary alcohols to carboxylic acids and secondary alcohols to ketones.<\/p>\n
Handling: Requires protective gear, including gloves, eye protection, and masks, as it is highly toxic and corrosive.<\/p>\n
Storage: Store in a tightly sealed container in a dry, well-ventilated area away from acids and combustible materials.<\/p>\n
Spillage: Clean spills immediately with appropriate protective equipment, avoiding direct contact and inhalation of dust.<\/p>\n","protected":false},"excerpt":{"rendered":"
