Radish red

Product Description:Dark red amorphous powder, easy to absorb moisture, moisture absorption after caking, and generally does not affect the use. Easily oxidized.Sunlight can promote its degradation and fade.Soluble in water and aqueous solution of ethanol, insoluble in non-polar solvents.This product is an aqueous solution with a pH of the medium increased the maximum absorption peak shift, the absorbance decreased.Solution hue with medium pH from 2.0 to 8.0 in turn presented: orange - pink - red - violet. Of an aqueous solution of the goods on the thermally unstable, with increasing temperature, accelerated degradation, in order to fade, but is more stable under acidic conditions. Cu2 + can accelerate its degradation, and make it into the blue; Fe3 + This product can be solution turns rust yellow; Mg2 +, Ca2 + to the chemicals; Al3 +, Sn2 + it has a protective effect.
