실험 절차

Taking material from Example 1, eight grams of sodium hexadecylsulfinate (0.026 moles) was dissolved in 300 ml deionized water at 45° to 50° C. When measured at 45° C. the pH was 9.0 and the millivolt reading, using a silver/silver sulfide electrode and a silver chloride/4M KCl reference electrode, was -24. The pH was adjusted to 6.9 with 1:20 HNO3 /H2O. A solution of 7 ml 3N AgNO3 and 200 ml H2O was added with stirring to this mixture in four portions of 50 ml each, stirring 2 minutes after each addition, and stirring 10 minutes after the final addition. Temperature was maintained at 40° to 45° C. The final mixture has a pH of 3.6 and a millivolt reading of +206° at 40° C. This corresponds to a pAg of 6.4.
