Fig. 3. Bromination of phenol red used to detect halogenating activity qualitatively. Owing to bromination, a marked color change occurs from yellow (at acidic to neutral pH) to deep blue or purple, which can easily be detected by eye. However, the marked color change allows visual screening...
When exposed to air and light, phenol turns a red or brown color, the color being influenced by the presence of metallic impurities. Oxidizing agents also hasten the color change. Aqueous solutions of phenol are stable. Oily solutions for injection may be sterilized in hermetically sealed containe...
When cells are transferred from the CO2 incubator to the often uncontrolled atmospheric conditions of the microscope stage for analysis, reduction of CO2 levels can lead to alkalinization of the medium in less than an hour, accompanied by a change in Phenol red color to pink and then purple....

Fe(III) ions possibly are bound first to the phenolate groups of 4MP-AuNPs, and further coordinated several nanoparticles via the carboxylate groups of TGA-AuNPs to cause aggregation, resulting in a red-to-purple color change and a bathochromic shift in the SPR absorption band of the nanoprobe...
This can happen when stored in places with some frequent temperature change, be it daily or weekly or so. When the ink has warmed up and the environment now cools down, some minor amount of water may condense at the top and slowly runs down, staying in the top layer of the ink. Wh...
