2. An extreme in sediment volume was used as a criterion for the effective cancellation of interparticle attraction by the continuous phase. Nylon 6,6 dispersions consisting of \( 1 \mathrm{~g} \) of solid in \( 10 \mathrm{ml} \) of \( \mathrm{n} \)-propanol-thiodiethanol mixtures of various compositions were allowed to settle to sedimentation equilibrium. Listed here are the equilibrium sediment volumes, the volume/volume compositions, and the surface tensions of the media. Plot the sediment volume versus the surface tension of the continuous phase for these dispersions. What is the apparent surface tension of the nylon 6,6 ?
