JUSTIFICATION FOR DATA WAIVING
As ferrous slags are UVCB, the definition for a dissociation constant does not apply to ferrous slags. Expert judgement based on knowledge of the manufacturing method and analytical data e.g. on the composition of slags
Furthermore the substance is highly insoluble making the study unfeasible.
