experimental study
Adequacy of study:
key study
Study period:
15.01.2013 to 29.01.2013
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
test procedure in accordance with national standard methods
Justification for type of information:
Experimental test result performed using standard test guidelines
Qualifier:
according to
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

Key result
Sample tested:
other: not specified (migrated information) ml or mg of KMnO4
Parameter:
other: ml or mg of KMnO4
Result:
511.2 other: mg/100g
Remarks on result:
other: No other detail available
Interpretation of results:
other: no oxidising properties
Conclusions:
Test chemical was determine to be oxidising since 511.2 ml of KMnO4 was required for getting the end point of the redox titration for 100 g of test chemical. However, this oxidising property is very mild and does not classify the chemical as an oxidising solid.
Executive summary:

Test chemical was determine to be oxidising since 511.2 ml of KMnO4 was required for getting the end point of the redox titration for 100 g of test chemical. However, this oxidising property is very mild and does not classify the chemical as an oxidising solid.

non oxidising

Additional information

Test chemical was determine to be oxidising since 511.2 ml of KMnO4 was required for getting the end point of the redox titration for 100 g of test chemical. However, this oxidising property is very mild and does not classify the chemical as an oxidising solid.

Justification for classification or non-classification

Test chemical was determine to be oxidising since 511.2 ml of KMnO4 was required for getting the end point of the redox titration for 100 g of test chemical. However, this oxidising property is very mild and does not classify the chemical as an oxidising solid.
