Summary

  1. (1)

    The solubility-composition isotherm for camphor-β-sulphonic acids at 35° has been determined and shown to consist of three curves indicating that the racemic modification is a truedl-compound.

  2. (2)

    The solubilities ofd- andl-camphor-β-sulphonic acids are equal at 35°.

  3. (3)

    The shape of the melting-point-composition diagram and the solubility-composition isotherm enables us to infer thatdl-camphor-β-sulphonic acid is stable and its range of stability is large.
