Additional information

In accordance with section 1 of REACH Annex XI, the dissociation constant study does not need to be conducted as the substance is a salt. Salts are reaction products of acids and bases that retain their ionic character.

So salts are never undissociated. The dissociation constant is only relevant for substances with a acid or basic character.
