Beschrijving

Phenolphthalein-indicatoroplossing 0.1 % in ethanol 90 %, gedenatureerd, is een klassieke zuur–base-indicatorbereiding voor titratie en pH-gerelateerd analytisch werk. De ethanolische oplossing heeft een dichtheid van 0.82 g/cm³, een vlampunt van 12 °C en een kookpunt van 78 °C, wat de op alcohol gebaseerde matrix weerspiegelt. Bij overgangen van neutraal naar alkalisch geeft phenolphthalein de vertrouwde kleurverandering waarop veel standaardtitratemethoden steunen. Deze indicatoroplossing van fabrikant Carl ROTH past bij milieuanalyse, algemene meetmethoden en routinematige laboratoriumtitratie waarin een gedenatureerd ethanolisch phenolphthalein-reagens is voorgeschreven. De gedefinieerde sterkte van 0.1 % ondersteunt consistente visuele eindpunten bij herhaalde bepalingen.

Dit artikel maakt deel uit van Oplosmiddelen van analytische kwaliteit (p.a.), in Oplosmiddelen.

Questions about Phenolphthalein-indicatoroplossing, 0.1 % in ethanol 90 %, gedenatureerd, 250 ml

What is this article?

Phenolphthalein-indicatoroplossing, 0.1 % in ethanol 90 %, gedenatureerd, 250 ml is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Oplosmiddelen van analytische kwaliteit (p.a.), inside Oplosmiddelen, in Chemicaliën.

An analytical-grade solvent, often marked p.a., has impurity limits tight enough for classical analysis and for preparing reagents. It is not automatically low enough in UV absorbance for HPLC, and it is not dry enough for a water-sensitive reaction. The grade is the purchase.

A solvent dissolves. The grade says which impurities are low enough for the method. Analytical grade is the ordinary pure solvent. HPLC and LC-MS grades limit the absorbance and the ions that would become peaks or background. A dry solvent has had water removed. A deuterated solvent is for NMR, where the hydrogen signal would otherwise drown the sample. Technical grade is for cleaning and for synthesis that does not need a chromatogram. Identity is on PubChem. Names follow IUPAC. Hazards follow ECHA, the CLP Regulation and REACH.
