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 Rc.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 Rd.f. from the density fluctuations on the system. The quantities Kc/Rc.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.
