New experimental data for the viscosity and density of the binary systems lithium chloride + water, lithium bromide + water, calcium chloride + water, lithium nitrate + water, and zinc bromide + water are presented. Densities are presented in tabular form and as 10-parameter correlations, while kinematic and dynamic viscosities are presented in tabular form. Data are presented in the concentration range from intermediate dilution to close to room temperature crystallization concentration. The temperature ranges are 20-70 degrees C for density and 25-90 degrees C for viscosity. When available, literature data are compared with the new data, and some disagreement is found. New thermogravimetric curves are presented for the dehydration of CaCl2, ZnBr2, and LiBr in order to enable evaluation of drying as a composition determination technique.
