Densities , refractive indices and specific refraction of potassium ferricynate (III) in acidic media at 29o C

Densities (r) and refractive indices (nD) of potassium Ferricynate(III) of different concentration (0.1 to 0.8N) aqueous 0.1 M HCL solution were measured at 290C. Specific refraction (RD) were calculated from refractive index and density of solutions. The measured refraction index and density were of calculated using Lorentz and Lorentz formula and andher, desai and joshi’s formula on comparison it predict the values were nearly to the Lorentz and Lorentz formula
