Description
ortho-Phosphoric acid 50 % is a pure mineral acid solution with CAS number 7664-38-2 and the empirical formula H₃PO₄. It carries EG number 231-633-2, a molar mass of 98,00 g/mol and a density of 1,33 g/cm³, while the boiling point is stated as 108 °C. These defined physicochemical values support accurate dilution calculations and process planning in the laboratory. The product is The pure grade designation matches the manufacturer data for everyday analytical and preparative use. Transport classification is indicated by UN number 1805. Density and molar mass enable straightforward conversion between mass, volume and molar concentration when preparing working solutions. The one-litre plastic format eases handling, dispensing and storage in chemical stores and on the laboratory bench for research, teaching and quality-control environments that require a clearly specified phosphoric acid concentration.

Questions about ortho-Phosphoric acid 50 %, pure, 1 l, plastic
What is this article?
ortho-Phosphoric acid 50 %, 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.
