Reference
Endpoint:
dissociation constant
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study without detailed documentation
Justification for type of information:
Company data, with assessment made according to accepted methods, but no GLP
Reference:
Composition 0
Principles of method if other than guideline:
A preparation of a 0.01 M aqueous solution of Cr2(C2O4)3 in deionised water was titrated with 0.1 N sodium hydroxide.
GLP compliance:
no
Test material information:
Composition 1
Dissociating properties:
yes
Remarks on result:
other: Not possible to determine
Remarks:
The data indicates that the substance does not show typical dissociation characteristics and behaves as a fully dissociated substance. The substance is highly soluble in water at all pH levels.

The substance appears to be full dissociated at all pH levels tested (ie biological and environmental conditions).

Conclusions:
A preparation of a 0.01 M aqueous solution of Cr2(C2O4)3 in deionised water was titrated with 0.1 N sodium hydroxide.
The data indicates that the substance does not show typical dissociation characteristics and behaves as a fully dissociated substance. The substance is highly soluble in water at all pH levels.
