Eriochrome Black T
Also known as: Acidchromeblacketn
Dark brown powder. It is soluble in water and is Zao red to oar red; slightly soluble in alcohol and brownish pinkish red; slightly soluble in acetone. It is dark blue in concentrated sulfuric acid, light red brown after dilution, and orange yellow in concentrated nitric acid. There was no significant change in the aqueous solution and concentrated hydrochloric acid; the concentrated sodium hydroxide solution turned brown and magenta. The solubility in water (90 ℃) is 25g / L. When dyeing, copper and iron are encountered, and the color light has great influence.

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.
