Description
ortho-Phosphoric acid 40 % is a pure aqueous phosphoric acid solution formulated for laboratory chemical work. The acid corresponds to CAS number 7664-38-2, empirical formula H₃PO₄ and molar mass 98,00 g/mol. At 40 % concentration the solution exhibits a density of 1,25 g/cm³ and a boiling point of 104 °C, Higher concentration relative to dilute grades makes it useful when stronger acidity or reduced water load is required in buffer systems, cleaning formulations, sample preparation or inorganic synthesis support. Density values assist conversion between volume and mass during solution make-up. Supplied from manufacturer Carl ROTH as part of the core chemicals portfolio, the product suits routine wet-chemistry environments in research, education and quality control. EG number 231-633-2 identifies the substance for regulatory and SDS-linked documentation. Always handle phosphoric acid solutions with suitable corrosion-resistant equipment and established laboratory safety measures.
This article is part of Acids, in Acids & bases.

Questions about ortho-Phosphoric acid 40 %, pure, 1 l, plastic
What is this article?
ortho-Phosphoric acid 40 %, 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.
Which category should I open next?
