Which one of the following is incorrect for ideal solution?
Mixing is spontaneous, so $\Delta G_{mix} < 0$.
For an ideal solution $\Delta H_{mix} = 0$, $\Delta U_{mix} = 0$ and $\Delta S_{mix} \ne 0$
According to $\Delta G_{mix} = \Delta H_{mix} - T\Delta S_{mix}$, $\Delta G_{mix} \ne 0$
So '$\Delta G_{mix} = 0$' is incorrect.
