The ‘Substance identity’ section is calculated from substance identification information from all ECHA databases. The substance identifiers displayed in the InfoCard are the best available substance name, EC number, CAS number and/or the molecular and structural formulas. Chromic acid can be prepared by adding concentrated sulfuric acid to a cooled aqueous solution of a dichromate salt: H2SO4 + K2Cr2O7 → H2CrO4 + K2SO. Very pure chromic acid can be made by adding chromium trioxide to pure water. By summarising this information in a single page, ECHA aims to make this information accessible in a user-friendly way in line with the Agency’s goals and standards. Data from all dossiers registered and the Classifications and Labelling Inventory (C&L) for the same substance are used to generate the Brief Profile.
