This study was aimed at providing information on the effects brought on by hypotonicity and supporting electrolytes on ionic strength and conductivity of physiological solutions. Isotonic and 50% hypotonic solutions of chloride and chloride+sulphate salts were prepared, taking into account their molecular weight and osmotic concentration. Their specific conductivity and molar conductivity were measured at 25°C using a pH/conductivity meter. There was a decrease in specific and molar conductivity of all the electrolyte studied as a result of 50% hypotonicity except for CaCl 2+CaSO4 solution. Tonicity had more effect on the molar conductivity of week electrolytes. The addition of supporting electrolyte resulted in an increase in the calculated ionic strength and molar conductivity. It also resulted in an increase in the specific conductivity of the resultant supported solutions except CaCl2+CaSO4 and MgCl2+MgSO4 solutions. The relative ionic strengths of the electrolytes could not be determined from their specific conductivity because the contribution of multivalent supporting electrolyte ions to ionic concentration is not evident in the specific conductivity of the resultant solutions.
