Reference
Endpoint:
oxidising solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
25.10.2012-06.11.2012
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
comparable to guideline study
Justification for type of information:
Experimental test result performed using standard test guidelines
Qualifier:
according to guideline
Guideline:
other: as mention below
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
