Question

Which condition is not satisfied by an ideal solution?

• A. ${\Delta }_{mix}V=0$
• B. ${\Delta }_{mix}S=0$
• C. Obeyance to Raoult’s Law
• D. ${\Delta }_{mix}H=0$

Answer 1

The correct option is B

${\Delta }_{mix}S=0$

An ideal solution follows:
. Volume change $\left(\Delta V\right)$ of mixing should be zero
. Heat change $\left(\Delta H\right)$ on mixing should be zero.
. Obeys Raoult’s law at every range of concentration.
