Sodium Chromate Tetrahydrate with CAS 10034-82-9
Sodium chromate is a yellow monoclinal crystal, which is easy to moisture. Soluble in water and methanol, slightly soluble in ethanol. It is oxidized and can be reduced to trivalent chromium. Used for making dyes, pigments, etc. It can be made by mixing ferrochrome powder, pure alkali and limestone powder at high temperature. Mainly used in ink, paint, pigment, metal corrosion inhibitor, organic synthetic oxidant, tannins and printing and dyeing. Used as analytical reagents, rust-proofing agents, mordants and tannins, as well as for organic synthesis, mainly for the manufacture of chemical reagents, chromates and pigments. Store in a cool, ventilated warehouse. Keep away from fire and heat. Prevent direct sunlight. Packing is sealed. It should be stored separately from reducing agent, inflammable and edible chemicals. The storage area shall be provided with suitable materials for containment of leakage.
