Pyrocatechol Violet
Also known as: PyrocatechinSulfonphthaleinViolet
Reddish brown crystalline powder. Soluble in water and water-containing alcohol, slightly soluble in cold anhydrous ethanol, insoluble in non-polar organic solvents (such as ether, benzene, xylene). The aqueous solution is yellow. When the acidity increases, it turns from yellow to red. When the pH is above 6, it turns to cyan purple. When the pH is above 9, it turns to purple red. The aqueous solution is stable, but easy to be oxidized by oxidant.

1,10-Phenanthroline Hydrate
O-phenanthroline (o-phenanthroline) is a commonly used redox indicator. As a simple, cheap and fast detection method, o-phenanthroline colorimetry is widely used in the detection and analysis of iron. The principle is that in the solution of pH = 3 ~ 9, o-phenanthrene and Fe2 + will form a stable orange red complex. The color depth of the complex can be used to determine the content of iron ions in the sample to be tested.
