SODIUM DI CHROMATE AR DIHYDRATE
SODIUM DICHROMATE AR DIHYDRATE
- Part number
- RXSOL-60-6605-497
- Category
- Lab Chemical
- Brand
- RXSOL
Overview
Sodium dichromate dihydrate can react with reducing agents to generate heat and products that may be gaseous (causing pressurization of closed containers). The products may themselves be capable of further reactions (such as combustion in the air). Reactions may be rapid but often requires initiation (heat, spark, catalyst, addition of a solvent).
Applications
Sodium dichromate appears as a red or red-orange crystalline solid. May be strongly irritating to skin, eyes and mucous membranes. Used as a corrosion inhibitor, and in the manufacture of other chemicals.
Characteristics and notes
Sodium dichromate is highly corrosive in nature and is a strong oxidizing agent. This substance is usually used to produce other chromium compounds but is also used for drilling muds, metal treatments, wood preservatives, production of dyes and organic chemicals, and as a corrosion inhibitor.
Safety and SDS
Read the safety data sheet before handling. Wear suitable gloves and eye protection.
