Materials and methods

Test guideline
Qualifier:
according to guideline
Guideline:
other:
Principles of method if other than guideline:
Redox titrations are based on a reduction-oxidation reaction between an oxidizing agent and a reducing agent. A potentiometer or a redox indicator is usually used to determine the endpoint of the titration. In permanganometry a slight faint persisting pink color signals the endpoint of the titration because of the color of the excess oxidizing agent potassium permanganate
GLP compliance:
no

Applicant's summary and conclusion

Interpretation of results:
other: mild oxidising property
Conclusions:
Sodium 3-methylsulphanilate was found to have mild oxidising property since 117.9 ml of KMnO4 was required for getting the end point of the redox titration for 100 g of sodium 3-methylsulphanilate.

Executive summary:

Sodium 3-methylsulphanilate was found to have mild oxidising property since 117.9 ml of KMnO4 was required for getting the end point of the redox titration for 100 g of sodium 3-methylsulphanilate.
