| | Sodium dichromate dihydrate Chemical Properties |
| | Sodium dichromate dihydrate Usage And Synthesis |
| Chemical Properties | Orange crystals or needles | | General Description | Solid orange-yellow crystal or powder. | | Air & Water Reactions | Water soluble (hot water). | | Reactivity Profile | 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. | | Health Hazard | INHALATION: Corrosive to mucous membranes continuous exposure may lead to perforation of nasal septum. EYES: Conjunctivitis and lacrimation. SKIN: Corrosive producing deep penetrating ulcers to exposed area. Slow to heal. INGESTION: Has a harsh metallic taste. May cause vertigo, thirst, abdominal pain, vomiting, shock, convulsions and coma. |
