📄 详细内容
Properties: Olive to dark olive-green coarse powder. Absorption max: 540-545 nm (10 mg/l of 0.01% HCl). Very sol in water, very slightly sol to insol in alcohol. Dil aq solns are purplish red. Very dil aq solns (1:10,000) are decolorized by drops of concd aq NaOH solns, but not returned by concd HCl. The decolorized soln neutralized with NaOH is called the
Andrade indicator. Changes from red to colorless at pH 12-14.
Absorption maximum: Absorption max: 540-545 nm (10 mg/l of 0.01% HCl)
Use: As pH indicator; biological stain.
