Abstract
The usefulness of chemical analysis as a supplement to sensilometric data is emphasized. Distribution ratios for hydroquinone and mitol between water and ether are given as functions of sulfite concentration and pH. A new analytical method is presented for the determination of metol and hydroquinone in a photographic solution where the developing agents are “salted out” of the solution at the proper pH by means of sodium thiosulfate and determined volumetrically by titration with iodine. A modified Volhard method is presented for the determination of soluble bromide where the interfering substances are removed by treatment with hydrogen peroxide.
