Beschreibung
Kaliumhydroxide-oplossing, Reag. Ph. Eur., is een 0,1 mol/l (0,1 N) volumetrische standaardoplossing van KOH voor titrimetrisch en analytisch werk waarbij reagentia van farmacopeekwaliteit vereist zijn. Het preparaat stemt overeen met CAS 1310-58-3 met de empirische formule KOH, molaire massa 56,11 g/mol, dichtheid 1,003 g/cm³ en kookpunt 100 °C. Geleverd in een verpakking van 1 liter, is het bedoeld als kant-en-klare volumetrische standaard voor zuur-basetitraties, standaardisatieprocedures en aanverwante anorganische analytische methoden in farmaceutische, chemische en kwaliteitscontrolelaboratoria. Deze waterige kaliumhydroxide-oplossing van fabrikant Carl ROTH voldoet aan de Reag. Ph. Eur.-aanduiding voor volumetrische standaardoplossingen en draagt EG-nr. 215-181-3. De gedefinieerde concentratie ondersteunt reproduceerbaar titratiewerk zonder dat vaste base ter plaatse hoeft te worden verdund. Geschikt voor routinematige en gereguleerde laboratoriumomgevingen die Ph. Eur.-reagenskwaliteit voorschrijven voor basen die als volumetrische standaard worden gebruikt.
Dit artikel hoort bij Basen & alkaliën, in Zuren & basen.

Questions about Kaliumhydroxide sol., Reag. Ph.Eur.
What is this article?
Kaliumhydroxide 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 Labor- und Industriechemikalien.
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?
