Description
Potassium hydroxide solution 45 % is an extra pure aqueous alkali with the empirical formula KOH, CAS number 1310-58-3 and a molar mass of 56,11 g/mol. The solution shows a density of 1,45 g/cm³ and a boiling point above 100 °C, providing laboratories with a strong, clearly specified base for analytical and synthetic tasks. The extra pure grade supports standard-solution work and routine procedures that benefit from consistent composition. This reagent from manufacturer Carl ROTH carries EG number 215-181-3 and UN number 1814, reflecting its status as a corrosive alkaline liquid that must be handled with appropriate protective equipment. The 45 % concentration enables straightforward dilution to working strengths while keeping stock volumes manageable. Research, teaching and quality-control environments can use this potassium hydroxide solution whenever a ready-to-dispense, high-strength KOH reagent is required for reliable alkaline chemistry.
This article is part of Bases & alkalis, in Acids & bases.

Questions about Potassium hydroxide solution 45 %, extra pure, 1 l, plastic
What is this article?
Potassium hydroxide solution 45 %, 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.
