Answer:
The two characteristics of ideal solution is:
(i) An ideal solution follows Raoult’s law and the components can be separated by fractional distillation.
(ii) ΔHmix = 0,
ΔVmix = 0,
A-A, B-B and A-B interactions of same length.
Answer:
A solution showing negtive deviation:
ΔH = –ve,
ΔV = – ve, Ptotal < P0A XA + P0B XB
Example: Solution of chloroform and acetone.
