✦ Synopsis

A comparison of sound velocity evaluated from Nomoto's relation, ideal mixing relation Jacobson's free length theory and Schaaffs' collision factor theory has been made in six binary molten clectrolytcs (NaCI-KCI, NaCI-RbCI, NaCI-CsCI, KCl-LiCI, KCI-RbCI, KCI-KBr) at 800°C. The agreement between theoretical and expernnental values is qurte satisfactory. Discrepancies m the sound velocity values are maximum in the case of NaCl-CsCl system where maximum interactions are observed. Non-ideality in the mixtures has been discussed in terms of sound veloctty.

Sipifiamt structure theory and Flory theory are succe.ssfulIy applied for evaluating the ultrasonic velocity in five molten alkali halides (NaCl, NaBr, KCI, KBr, and KI). Later theory provides better estimates and the theoretical results are in fairly good agreement with experimental findings. Hard
