Question
An ideal solution is formed when its components
A.
have no volume change on mixing
B.
have no enthalpy change on mixing
C.
have both the above characteristics
D.
have high solubility
Answer :
have both the above characteristics
Solution :
In ideal solution there is no change in enthalpy and volume after mixing, i.e.
$$\eqalign{
& \Delta {V_{{\text{mixing}}}} = 0,\,\Delta {H_{{\text{mixing}}}} = 0 \cr
& {\text{and}}\,\,\,{T_{{\text{mix}}}} = 0 \cr} $$
