Sažetak
The apparent molar volumes of monosodium salts of aliphatic dicarboxylic acids of the HOOC(CH2)n(COOH)2 [n = 0 – 5] types in dilute aqueous solution have been determined by precise density measurements, at T = 298.15 K. Densities were measured using a vibrating-tube densimeter (DMA 5000, Anton Paar, Austria) at T = 298.15 K. These results were used to calculate the apparent molar volumes of each solute over the concentration range 0.0050 ≤ m /(mol • kg-1) ≤ 0.3000. A new method for determining the values of partial molar volume of the electrolyte of NaHA type has been proposed. This method takes into account all equilibrium occurring in the solution. The variations of partial molar volume values with aliphatic chain length of analyzed salts were determined.
