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.
