The solubilities of rubidium nitrate in water, water plus methanol, and water plus ethanol have been determined using a simple accurate analytical method at different temperatures. In all cases, the presence of either methanol or ethanol significantly reduced the solubility of rubidium nitrate in aqueous solution. A four‐parameter equation was adjusted to the experimental data satisfactorily. Refractive index was also determined for the two ternary systems both in saturated and unsaturated solutions with varied salt concentrations. Furthermore the values for refractive index were correlated with the proportions of alcohol and the concentrations of salt.
