For an ideal solution Δ H and Δ V for mixing should be zero. PTotal = pA + pB and A - A, B - B and A -B interactions are nearly same.

Q. What are the conditions for an ideal solution which obeys Raoult’s law over the entire range of concentration?

$Δ_{mi x} H = 0$ , $Δ_{mi x} V = 0$ , $P_{T o t a l} = p_{A}^{\circ} x_{A} + p_{B}^{\circ} x_{B}$

$Δ_{mi x} H = + v e$ , $Δ_{mi x} V = 0$ , $P_{T o t a l} = p_{A}^{\circ} x_{A} + p_{B}^{\circ} x_{B}$

$Δ_{mi x} H = 0$ , $Δ_{mi x} V = + v e$ , $P_{T o t a l} = p_{A}^{\circ} x_{A} + p_{B}^{\circ} x_{B}$

$Δ_{mi x} H = 0$ , $Δ_{mi x} V = 0$ , $P_{T o t a l} = p_{B}^{\circ} x_{B}$

For an ideal solution $Δ H$ and $Δ V$ for mixing should be zero. $P_{T o t a l} = p_{A} + p_{B}$ and $A - A$ , $B - B$ and $A - B$ interactions are nearly same.

Δmix​H=0, Δmix​V=0, PTotal​=pA∘​xA​+pB∘​xB​

Δmix​H=+ve, Δmix​V=0, PTotal​=pA∘​xA​+pB∘​xB​

Δmix​H=0, Δmix​V=+ve, PTotal​=pA∘​xA​+pB∘​xB​

Δmix​H=0, Δmix​V=0, PTotal​=pB∘​xB​

For an ideal solution ΔH and ΔV for mixing should be zero. PTotal​=pA​+pB​ and A−A, B−B and A−B interactions are nearly same.

$Δ_{mi x} H = 0$ , $Δ_{mi x} V = 0$ , $P_{T o t a l} = p_{A}^{\circ} x_{A} + p_{B}^{\circ} x_{B}$

$Δ_{mi x} H = + v e$ , $Δ_{mi x} V = 0$ , $P_{T o t a l} = p_{A}^{\circ} x_{A} + p_{B}^{\circ} x_{B}$

$Δ_{mi x} H = 0$ , $Δ_{mi x} V = + v e$ , $P_{T o t a l} = p_{A}^{\circ} x_{A} + p_{B}^{\circ} x_{B}$

$Δ_{mi x} H = 0$ , $Δ_{mi x} V = 0$ , $P_{T o t a l} = p_{B}^{\circ} x_{B}$

For an ideal solution $Δ H$ and $Δ V$ for mixing should be zero. $P_{T o t a l} = p_{A} + p_{B}$ and $A - A$ , $B - B$ and $A - B$ interactions are nearly same.
