Procedure

0.1 g Crystal Violet is dissolved in 100 mL acetic acid to obtain a Crystal Violet solution. 8.5 mL perchloric acid is slowly added with mixing to a solution that has been preliminarily prepared by mixing 500 mL acetic acid with 200 mL acetic anhydride. This is brought to a total of 1 L by the addition of acetic acid and is then allowed to stand for 3 days to give a perchloric acid/acetic acid solution. The factor for this perchloric acid/acetic acid solution is determined as follows: 0.1 g potassium hydrogen phthalate is weighed to 1 mg and is dissolved in 20 mL acetic acid; 90 mL o-nitrotoluene is then added; several drops of the Crystal Violet solution are added and titration is performed with the perchloric acid/acetic acid solution; and the factor is determined from the amount of perchloric acid/acetic acid solution required for neutralization.
