Definition of density and concentration of water solutions of salts in the optical way (the example of lithium bromide)

Optical method definition the water density and concentration of lithium bromide solutions using changes of a refraction index are presented. Values of the refraction index for LiBr solution in depending from concentration and temperature for wave lengths λ =0,66 micron and λ =0,532 micron are received at change of concentration from 0 to 60 %.
