Fuchsin Acid - Introduction
This product is a mixture of sodium bisulfonate (Rosaniline), sodium trisulfonate and ammonium salt. It is a dark red powder with green metallic luster or olive to dark olive green coarse powder or small pieces. 1g is soluble in 7ml of water and slightly soluble in ethanol. The dilute aqueous solution is purplish red, and the extremely dilute aqueous solution (1:10000) is dropped into the concentrated sodium hydroxide solution to fade, but it does not fade to concentrated hydrochloric acid. The red to colorless pH is 12-14. The maximum absorption wavelength is 540-545nm(10mg/L,0 · 01% hydrochloric acid). It's irritating.
