Description

Uses Cell stain Uses as acid-base indicator Uses acid-base indicator, pH discoloration range 3.8(yellow) to 5.4(blue-green) uses acid-base indicator. Colorimetric determination of pH is often used with sodium salts. Ph indicator, pHChemicalbook value 3.8 (yellow) ~ 5.4 (blue). Its sodium brine solution is used as a chromogenic agent for spectrophotometric determination of pH value. Used as a reagent for the determination of aliphatic acid and alkaloid by thin layer chromatography and as an extraction separation agent for the determination of quaternary ammonium cation by spectrophotometry.
