Use
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). Can react violently with active metals, cyanides, esters, and thiocyanates.
