Sodium chromate Usage And Synthesis
  • Chemical PropertiesYellow crystals or crystalline powder
  • Chemical PropertiesSodium chromate, including the hexahydrate, is yellow crystalline solids that can also be used in solution. Disodium dichromate (10588-01-9):
  • UsesDiagnostic aid (blood volume determination); radioactive agent.
  • DefinitionChEBI: An inorganic sodium salt consisting of sodium and chromate ions in a 2:1 ratio.
  • brand nameChromitope Sodium (Bristol-Myers Squibb); Rachromate (Abbott).
  • General DescriptionSodium chromate is a yellow crystalline solid dissolved in a liquid medium, probably water. Sodium chromate is soluble in water. Sodium chromate is toxic by inhalation, ingestion and/or skin contact. Sodium chromate is noncombustible. Sodium chromate is used to make pigments for paints and inks, other chemicals, and as a wood preservative.
  • Air & Water ReactionsWater soluble.
  • Reactivity ProfileSODIUM CHROMATE is a strong oxidizer. Sodium chromate 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].
  • HazardToxic material.
  • Health HazardHighly 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.
  • Fire HazardNon-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.
  • Potential ExposureUsed 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.
  • ShippingUN3087 Oxidizing solid, toxic, n.o.s., Hazard Class: 5.1; Labels: 5.1-Oxidizer, 6.1-Poisonous materials, Technical Name Required. UN3085 Oxidizing solid, corrosive, n.o.s., Hazard Class: 5.1; Labels: 5.1-Oxidizer, 8-Corrosive material, Technical Name Required.
  • IncompatibilitiesAqueous solution in a base. A strong oxidizer. Violent reaction with reducing agents; combustibles, strong acids; organic materials.
