Materials and methods

Test guideline
Qualifier:
according to
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: mildly oxidising
Conclusions:
3-amino-4-hydroxybenzenesulphonic acid was found to have mild oxidising property since 183.3 ml of KMnO4 was required for getting the end point of the redox titration for 100 g of 3-amino-4-hydroxybenzenesulphonic acid.
