Titrimetric determination of ascorbic acid with 2,6-dichlorophenol indophenol in commercial liquid diets.
The titrimetric determination of ascorbic acid in the presence of a variety of potentially physically and chemically interfering species in commercial liquid diets is presented. The titrant and indicator was a solution of 2,6-dichlorophenol indophenol. Iron(II), copper(II), cysteine, glutathione, sulfite, and tin(II) do not interfere.
