Beschreibung:   Phenolphthalein is an acid base indicator. It is a weak acid, which is colorless in acidic solution and turns puce pink in alkaline solution. Phenolphthalein is genotoxic. It might cause oxidative damage and binds to estrogen receptors. Phenolphthalein solution is a synthetic indicator. It is colorless in acidic and neutral conditions. Phenolphthalein gives pink color when added to a base, therefore it is considered as a base indicator.

Beschreibung:   Gram’s safranin solution, also known as Safranin T or Basic Red 2, is a ready-to-use staining solution that comprises 10% safranin in ethanol. Safranin is a basic, cationic, azine dye containing a planar, diaminophenazine chromophore, with a phenyl substituent attached to a ring nitrogen. The trimethyl cationic form of safranine is lipophilic, whereas the dimethyl forms are weakly hydrophilic. It is most notably used in bacteriology as a counterstain in Gram staining to differentiate between Gram-positive and Gram-negative bacteria.
