Questions about Solution de Sodium hydroxide, min. 32 %, extra pur, 1 l, plastique
What is this article?
Solution de Sodium hydroxide, min. 32 %, extra pur, 1 l, plastique is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Bases & alcalis, inside Acides & bases, in Produits chimiques.
A base or an alkali is sodium hydroxide, potassium hydroxide, ammonia and their relatives, as solid or as solution. The carbonate that a hydroxide picks up from the air changes a titre. Concentration and purity are the specification. Concentrated alkalis attack skin and aluminium.
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.
