Beschrijving
Methyl orange-indicatoroplossing is een kant-en-klare waterige bereiding van 0.1 % voor titratie en pH-indicatie. De oplossing heeft een dichtheid van 1 g/cm³ en een kookpunt van 100 °C, in overeenstemming met een indicator medium op waterbasis. Zij behoort tot de groep kant-en-klare pH-indicatoroplossingen die worden gebruikt bij zuur–basetitratie en routinematig analytisch werk waarbij een duidelijk visueel eindpunt vereist is. De waterige matrix ondersteunt directe toevoeging aan titratievaten zonder tussenliggende weeg- of oplosstappen. Als klassiek methyl orange-systeem in water past zij bij gevestigde protocollen voor het volgen van zuurteveranderingen tijdens volumetrische analyse.
Dit artikel maakt deel uit van Indicatoren & indicatoroplossingen, in Analytische standaarden & referentiematerialen.

Questions about Methyl orange-indicatoroplossing, 0.1 % in water, 500 ml, kunststof
What is this article?
Methyl orange-indicatoroplossing, 0.1 % in water, 500 ml, kunststof is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Indicatoren & indicatoroplossingen, inside Analytische standaarden & referentiematerialen, in Chemicaliën.
An indicator solution changes colour at a stated point, usually a pH interval or a redox potential, so a titration endpoint can be seen. The solvent and the concentration decide how sharp the change is. A solid indicator dye and a ready solution are different articles.
A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.

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.
