Description
Potassium hydroxide solution 50 %, extra pure is a concentrated aqueous KOH reagent with CAS number 1310-58-3 and empirical formula KOH. Key data include a molar mass of 56,11 g/mol, a density of 1,5 g/cm³ and a boiling point above 100 °C. The solution is Offered by manufacturer Carl ROTH, it supports titrations, pH adjustment, saponification, scrubbing steps and preparation of diluted working solutions in analytical and preparative chemistry. Its EG number is 215-181-3. The 50 % concentration provides a convenient, space-efficient base for further dilution under controlled conditions. Consistent extra pure quality helps laboratories obtain reproducible results in routine quality control, synthesis support and general wet-chemical procedures that depend on reliable potassium hydroxide solution.

Questions about Potassium hydroxide solution 50 %, extra pure, 1 l, plastic
What is this article?
Potassium hydroxide solution 50 %, 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.
