Description
ortho-Phosphoric acid 85 % is an extra pure inorganic acid with the empirical formula H₃PO₄ and CAS number 7664-38-2. It offers a molar mass of 98,00 g/mol, a density in the range 1,689 to 1,71 g/cm³, and a boiling point of 158 °C, making it a concentrated mineral acid for demanding laboratory work. This grade is Laboratories rely on it for organic synthesis, acidification steps, buffer systems, and cleaning routines that call for a strong Lewis acid with consistent strength. The material from manufacturer Carl ROTH is identified by EG number 231-633-2 and UN number 1805 for transport classification. Extra pure quality supports reproducible results in analytical and preparative workflows where impurity control matters. The ready liquid format integrates smoothly into fume-hood procedures and standard acid-handling protocols, giving chemists a dependable phosphoric acid source for synthesis reagents and related applications across research and industrial laboratories.

Questions about ortho-Phosphoric acid 85 %, 85 %, extra pure, 1 l, plastic
What is this article?
ortho-Phosphoric acid 85 %, 85 %, extra pure, 1 l, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Acids, inside Acids & bases, in Lab chemicals.
An acid on this shelf is the substance itself, concentrated or as a stated solution: hydrochloric, sulfuric, nitric, acetic and the rest. Concentration, purity and the trace metals decide the use. A concentrated acid and a volumetric solution of the same name are different products, and both burn.
An acid donates a proton. A base accepts one. In the bottle, the practical differences are the concentration, the purity and the anion or cation that comes along. Concentrated mineral acids are a different article from a dilute volumetric solution. The water in the acid, and the trace metals, decide whether it can be used for analysis. Check the substance on PubChem and the classification on ECHA CLP. Transport is the UNECE dangerous-goods framework. The legal texts are the CLP Regulation and REACH.
