The paper deals with correlation of density of aqueous solutions of NaOH, KOH, Na2CO3, and K2CO3 using an equation based on the additivity of molar volumes of components, the components being water and so-called basic electrolyte solution with precisely defined and measurable properties. The procedure mentioned has been tested at 20 °C using literature data. The procedure has been shown to give very precise results.
