A study of the heats of reaction of the binary mixture ether - chloroform

The reasons causing temperature and volume changes due to the mixing of non-aqueous liquids are varied. The phenomenon is probably complex because of the processes that may happen during true solution such as association, disassociation, chemical combination and thermal deassociation. Should these...
