Refractive Indices of Sodium, Potassium, and Ammonium Sulfates in Ethanol−Water Solutions

Refractive Indices of Sodium, Potassium, and Ammonium Sulfates in Ethanol−Water Solutions

The refractive indices (sodium line) of sodium, potassium, and ammonium sulfate in water and ethanol + water solutions have been determined experimentally over the temperature range (288.15 to 318.15) K and at atmospheric pressure. Parameters of polynomial equations which represent the composition d...

Description
Summary:The refractive indices (sodium line) of sodium, potassium, and ammonium sulfate in water and ethanol + water solutions have been determined experimentally over the temperature range (288.15 to 318.15) K and at atmospheric pressure. Parameters of polynomial equations which represent the composition dependence are gathered. The predicted results show good agreement with the experimental data.
