Questions about 5.5'-Dithio-bis-(2-nitrobenzoic acid), min. 98 %, p.a., 1 g, verre
What is this article?
5.5'-Dithio-bis-(2-nitrobenzoic acid), min. 98 %, p.a., 1 g, verre is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Acides, inside Acides & bases, in Produits chimiques.
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.
