| Hazard Information | Back Directory | [General Description]
Sodium chromate is a yellow crystalline solid dissolved in a liquid medium, probably water. SODIUM CHROMATE SOLUTION(7775-11-3) is soluble in water. SODIUM CHROMATE SOLUTION(7775-11-3) is toxic by inhalation, ingestion and/or skin contact. SODIUM CHROMATE SOLUTION(7775-11-3) is noncombustible. SODIUM CHROMATE SOLUTION(7775-11-3) is used to make pigments for paints and inks, other chemicals, and as a wood preservative. | [Reactivity Profile]
SODIUM CHROMATE is a strong oxidizer. This chemical absorbs moisture from the atmosphere. Incompatible with strong acids . In contact with combustible materials may cause fire. Toxic chromium oxide fumes may form in fire [USCG, 1999]. | [Air & Water Reactions]
Water soluble. | [Hazard]
Toxic material.
| [Health Hazard]
Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. | [Potential Exposure]
Used to make dyes, inks, pigments, and other chromates; in leather tanning, a corrosion inhibitor in circulating water systems; metal treatment; a drilling mud additive; chemical intermediate for chromium catalysts; colorimetry, oxidizing agent; bleaching agent; an algicide, fungicide, insecticide; in wood preservation. | [Fire Hazard]
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Containers may explode when heated. Runoff may pollute waterways. | [First aid]
If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. If victim is conscious, administer water, or milk. Do not induce vomiting. | [Shipping]

Aqueous solution in a base. A strong oxidizer. Violent reaction with reducing agents; combustibles, strong acids; organic materials. | [Chemical Properties]
Sodium chromate, including the hexahydrate, is yellow crystalline solids that can also be used in solution. Disodium dichromate (10588-01-9): | [Chemical Properties]
Yellow crystals or crystalline powder | [Uses]
Diagnostic aid (blood volume determination); radioactive agent. | [Uses]
Sodium chromate anhydrous is used as a corrosion inhibitor in the petroleum industry, wood preservative and dyeing auxiliary in the textile industry. It is also used to prepare pigments for paints and inks. It also finds use in pharmaceuticals to determine red blood cell volume. In synthetic chemistry, it is utilized as an oxidant to convert primary alcohols and secondary alcohols to carboxylic acids and ketones respectively. | [Definition]
