In aqueous solution, mercuri‐sulphosalicylic acid is present in a chain structure form, the chain formation being due to weak ionic interaction between the mercury of one molecule and the sulphonic acid group of another molecule. The conductance and pH studies support this structure. The substitution of mercury in sulphosalicylic acid increases the pK value for the dissociation of the phenolic hydrogen, the value being 12.34 at an ionic strength of 0.1.
