Description

La solution indicatrice de Phenolphthalein 0.1 % dans l'éthanol 90 %, dénaturé, est une préparation indicatrice acide–base classique pour le titrage et le travail analytique lié au pH. La solution éthanolique présente une densité de 0.82 g/cm³, un point d'éclair de 12 °C et un point d'ébullition de 78 °C, ce qui reflète sa matrice à base d'alcool. Lors des transitions du neutre à l'alcalin, phenolphthalein fournit le changement de couleur familier sur lequel reposent de nombreuses méthodes de titrage normalisées. Cette solution indicatrice du fabricant Carl ROTH convient à l'analyse environnementale, aux méthodes générales de mesure et au titrage courant en laboratoire lorsqu'un réactif éthanolique dénaturé de phenolphthalein est spécifié. La concentration définie de 0.1 % favorise des points finaux visuels réguliers lors de déterminations répétées.

Cet article fait partie de Solvants de qualité analytique (p.a.), dans Solvants.

Questions about Solution indicatrice de Phenolphthalein, 0.1 % dans l'éthanol 90 %, dénaturé, 250 ml

What is this article?

Solution indicatrice de Phenolphthalein, 0.1 % dans l'éthanol 90 %, dénaturé, 250 ml is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Solvants de qualité analytique (p.a.), inside Solvants, in Produits chimiques.

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.
