JUSTIFICATION FOR DATA WAIVING

The substance does not contain relevant functional groups for which an assessment of the dissociation behaviour would provide information for risk assessment purposes. Lead dichloride is a readily water soluble (10 g/L at 20°C) inorganic salt, yielding only inorganic ions upon dissolution. Therefore, the determination of a dissociation constant is not considered to be required (Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance, section R.7.1.17.1), and the study is waived on the basis of intrinsic chemistry.
