Description
Potassium hydroxide solution, Reag. Ph. Eur., is a 0,1 mol/l (0,1 N) volumetric standard solution of KOH for titrimetric and analytical work requiring pharmacopoeia-grade reagents. The preparation corresponds to CAS 1310-58-3 with empirical formula KOH, molar mass 56,11 g/mol, density 1,003 g/cm³ and boiling point 100 °C. Supplied in a 1 liter pack, it is intended as a ready-to-use volumetric standard for acid–base titrations, standardisation procedures and related inorganic analytical methods in pharmaceutical, chemical and quality-control laboratories. This aqueous potassium hydroxide solution from manufacturer Carl ROTH meets Reag. Ph. Eur. designation for volumetric standard solutions and carries EG nr. 215-181-3. The defined concentration supports reproducible titre work without on-site dilution of solid base. Suitable for routine and regulated laboratory environments that specify Ph. Eur. reagent quality for bases used as volumetric standards.
This article is part of Bases & alkalis, in Acids & bases.

Questions about Potassium hydroxide sol., Reag. Ph.Eur.
What is this article?
Potassium hydroxide sol., Reag. Ph.Eur. 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.
Which category should I open next?
The category is Acids & bases. The sub-category is Bases & alkalis. The catalogue is Lab chemicals.
Shelves beside this one are Acids.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
