Abstract

The Rayleigh ratio of the light scattered at 90° by solutions of three simple electrolytes has been measured with high precision using a modified Brice Phoenix light-scattering photometer. From the results obtained at wavelengths 546 and 436 mμ the contribution R_c.f. to the scattering due to fluctuations in concentration of the solute has been calculated from the total isotropic scattering of the solutions and the contribution R_d.f. from the density fluctuations on the system. The quantities Kc/R_c.f. so obtained are compared with (-∂ ln a₀/∂c)_p,Τ obtained from activity data. Also included are measurements on the refractive index, refractive index increment and depolarization of the solutions at wavelengths 546 and 436 mμ.
