As learnt

Condition of ideality -

Interaction between A - A; B - B are similar to A - B Interactions.

eg. Hexane + Heptone

Benzene + Toluere

- wherein

\Delta H_{mix}= 0

\Delta V_{mix}= 0

\Delta H - Change \: in\: enthalpy

\Delta V - Change \: in\: volume

 

 

 

Conditions for ideality for a solution are:

\\ \Delta H_{mix} \: > \: 0 \\ \\ \Delta V_{mix} \: > \: 0

Also, an ideal solution always Raoult's Law
