Questions about Indicators & indicator solutions

Why Indicators & indicator solutions?

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.
