Description
Sodium hydroxide solution 0,5 % is an extra pure aqueous laboratory reagent based on the empirical formula NaOH (CAS number 1310-73-2). With a molar mass of 40,01 g/mol, a density of 1 g/cm³ and a boiling point of 100 °C, this dilute caustic solution is suited to routine analytical, titration and general wet-chemistry work where a mild alkaline medium is required. The grade is specified as extra pure and carries EG nr. 215-185-5; the associated UN number is 1824. It is This sodium hydroxide solution from manufacturer Carl ROTH supports preparation of buffers, pH adjustment, cleaning protocols and other laboratory procedures that call for a defined 0,5 %. NaOH concentration. Clear labelling of concentration and purity helps maintain reproducibility across experimental and quality-control workflows in chemical and life-science laboratories.
This article belongs on Bases & alkalis, in Acids & bases.

Questions about Sodium hydroxide solution 0,5 %, 0,5 %, extra pure, 1 l, plastic
What is this article?
Sodium hydroxide solution 0,5 %, 0,5 %, extra pure, 1 l, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Bases & alkalis, inside Acids & bases, in Lab chemicals.
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.
