Abstract: Effect of mixed electrolytes (KCl + KBr), (KCl + KI) and (KBr + KI) on the temperature of sound velocity maximum (TSVM) of water, Tw, has been studied by determining the ultrasonic velocity with an accuracy of ± 0.003% using single crystal variable path interferometer working at 3 MHz. The velocity measurements were carried out at ; 2°C intervals over a range of 5°C on either side of TSVM of the solution. The accuracy in fixing TSVM is ± 0.2°C. The structural contribution to the shift in Tw of pure water due to the addition of mixed electrolytes, Tstr, has been found to be negative and increasing with concentration of mixed electrolytes. At any given concentration Tstr of (KCl + KBr) > (KCl + KI) > (KBr + KI). Tstr is also found to vary linearly with ionic strength of the mixed electrolyte solutions, and at any given ionic strength Tstr of (KCl + KBr) > (KCl + KI) > (KBr + KI). The results are explained in terms of enhancement in the structure breaking nature of Cl-, Br- and I- due to K+ and is found to be in the order of I- > Br- > Cl-.
