Produces violet (dilute) or green (concentrated) acid solutions|Greasy feel; also exists in hygroscopic, soluble, peach-blossom colored form|Greenish-black or violet deliquescent crystals, depending on whether chlorine is coordinated with the chromium. Density: 1.76; MP: 83 °C. Soluble in water and alcohol; insoluble in ether /Chromium chloride hexahydrate/|pH = 2.61 at 20 °C at a concentration of 50/g/L /Chromium chloride hexahydrate/|Chromium forms a number of compounds in various oxidation states. Those of 2+ (chromous), 3+ (chromic) and 6+ (chromates) are the most important /Chromium, alloys and cmpd/|Cr(III) is the most stable oxidation state of chromium & is always present as a coordination complex /Trivalent chromium/|For more Other Experimental Properties (Complete) data for Chromium (III) chloride (6 total), please visit the HSDB record page.

The rate of solution for water is extremely slow, pH of 0.2 M. aqueous solution is 2.4.

Non-Redox-Active Inorganic Compounds

When heated to decomposition, CHROMIC CHLORIDE emits toxic fumes of chlorine containing compounds. Violent reaction with lithium, nitrogen. Incompatible with strong oxidizers. [EPA, 1998].

Product: Offer surplus and non-recyclable solutions to a licensed disposal company. Contact a licensed professional waste disposal service to dispose of this material. Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. Contaminated packaging: Dispose of as unused product|Generators of waste (equal to or greater than 100 kg/mo) containing this contaminant, EPA hazardous waste number D007, must conform with USEPA regulations in storage, transportation, treatment and disposal of waste. /Chromium/|SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a permitted wastewater treatment facility is acceptable only after review by the governing authority and assurance that "pass through" violations will not occur. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal. If it is not practicable to manage the chemical in this fashion, it must be evaluated in accordance with EPA 40 CFR Part 261, specifically Subpart B, in order to determine the appropriate local, state and federal requirements for disposal.|The following wastewater treatment technology has been investigated for chromium: Concentration process: Biological Treatment. /Chromium/|For more Disposal Methods (Complete) data for Chromium (III) chloride (8 total), please visit the HSDB record page.
