Table 3 of Annex VI to CLP Regulation); and (2) the Candidate List of substances of very high concern (SVHC). This substance is used in the following areas: formulation of mixtures and/or re-packaging and scientific research and development. Chemical Agents: Annexes I & II, Dir. 2K 2 CrO 4 + H 2 SO 4 → K 2 Cr 2 O 7 + K 2 SO 4 + H 2 O [ Check the balance ] Potassium chromate react with sulfuric acid to produce potassium dichromate, potassium sulfate and water. Thermodynamic properties of substances The solubility of the substances Periodic table of elements. Use descriptors are adapted from ECHA guidance to improve readability and may not correspond textually to descriptor codes described in Chapter R.12: Use Descriptor system of ECHA Guidance on information requirements and chemical safety assessment. It is a common laboratory chemical, whereas sodium chromate is important industrially. 2(b)(i) - Hazardous Agents, EU Ecolabels - Restrictions for Hazardous Substances/Mixtures, Protection of Pregnant and Breastfeeding Workers Directive, Annex I+II, Workplace Signs - minimum requirements & signs on containers and pipes, Waste Framework Directive, Annex III - Waste - Hazardous Properties, Carc and Muta Directive, Annex I - Substances, Mixtures & Processes, Fertiliser Regulation- Annex I, E.3 (chelating and complexing agents), Candidate List, Authorisation list, Pre-Registration process, Other, CAD - Chemical Agents Directive, Art. Substances for which authorisation is required to be allowed to use the substance. POTASSIUM CHROMATE, >=99.0%, A.C.S. Please note that it may take a week or two to have everything fully in place, and please be aware in the meantime that the Registration status may be incorrect and the CLP regulatory context may be incompletely shown. Regulamentul privind procedura de consimțământ prealabil în cunoștință de cauză reglementează importul și exportul anumitor produse chimice periculoase și impune obligații întreprinderilor care intenționează să exporte astfel de produse în țări din afara UE. In these cases, Infocards may not identify all substances in the group.Therefore it does not represent official and legally–binding information. the electronic edition of the Official Journal of the European Union should be consulted.

Here you can find all of the regulations and regulatory lists in which this substance appears, according to the data available to ECHA. Gerd Anger, Jost Halstenberg, Klaus Hochgeschwender, Christoph Scherhag, Ulrich Korallus, Herbert Knopf, Peter Schmidt, Manfred Ohlinger, "Chromium Compounds" in Ullmann's Encyclopedia of Industrial Chemistry, Wiley-VCH, Weinheim, 2005. Such notifications are required for hazardous substances, mixtures, or articles, manufactured or imported at over 1 kg per annum. To confirm if a substance is covered by a specific regulatory action the official publication, e.g. The date of the last update corresponds to the publication date of the InfoCard and not necessarily to the date in which the update occurred in the source data. It is also used as an indicator in precipitation titrations with silver nitrate and sodium chloride (they can be used as standard as well as titrant for each other) as potassium chromate turns red in the presence of excess of silver ions. inside a watch) or with very low concentrations considered not to pose risks to human health or the environment. Now let us look at the chromate formula or chromate anion formula. Unlike the less expensive sodium salt, potassium salt is mainly used for laboratory work in situations where an anhydrous salt is required. The formula provides the following information: there are two potassiums, 1 chromium, and 4 oxygens. Tarapacaite is the natural, mineral form of potassium chromate. The molecular formula identifies each type of element by its chemical symbol and identifies the number of atoms of each element found in one discrete molecule of the substance. CHROMIUM(VI) ATOMIC SPECTR. 2, Dir 2004/37/EC (CMD), as amended by Dir 2019/130/EU, 31 Jan 2019, EU. The CAS number is the substance numerical identifier assigned by the Chemical Abstracts Service, a division of the American Chemical Society, to substances registered in the CAS registry database. The molecular structure is based on structures generated from information available in ECHA’s databases. in case of consumer and professional uses). The EC or list number is the primary substance identifier used by ECHA. Potassium chromate is the inorganic compound with the formula (K2CrO4). the electronic edition of the Official Journal of the European Union. This list is generated from hazardous substances listed in Directive 92/85/EEC and from table 3.2 of Annex VI of the CLP. The annexes to this directive provide detailed information about the minimum requirements for all safety and health signs. This substance has been found in the following regulatory activities (directly, or inheriting the regulatory context of a parent substance): This list represents a calculated inventory of substances based on the list of harmonized substances contained in Table 3 of Annex VI to the CLP Regulation (1272/2008/EC). +Add Attachment The described Product category (i.e. The formula for potassium chromate is: K2CrO4.
