Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Reference
Endpoint:
water solubility
Type of information:
experimental study
Adequacy of study:
key study
Study period:
May 2020
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
comparable to guideline study
Qualifier:
no guideline followed
Guideline:
other: Titration with oxalic acid
Principles of method if other than guideline:
Principle of test:
A solution of oxalic acid was prepared. A defined volume of the oxalic acid solution was acidified with sulfuric acid, heated to 80 °C and then titrated with the
permanganic acid solution.
The intense violet color of the permanganic acid disappears as long as oxalic acid is present. After complete oxidation of the oxalic acid with permanganic acid, the appearing violet color indicates the end of the titration.
With the known concentration and volume of the oxalic acid and the known volume of the needed permanganic acid, the concentration of the permanganic acid can be calculated.
GLP compliance:
no
Type of method:
other: Titration
Key result
