(A) According to Raoult's law,the total pressure $P$ of a solution containing two volatile components $A$ and $B$ is given by: $P = P_A + P_B$ Since $P_A = X_A P_A^o$ and $P_B = X_B P_B^o$,we have: $P = X_A P_A^o + X_B P_B^o$ Substituting $X_B = 1 - X_A$: $P = X_A P_A^o + (1 - X_A) P_B^o$ $P = X_A P_A^o + P_B^o - X_A P_B^o$ $P = X_A (P_A^o - P_B^o) + P_B^o$ This equation is derived directly from Raoult's law,which defines an $Ideal$ solution.

For a solution of two liquids $A$ and $B$,if $P = X_A (P_A^o - P_B^o) + P_B^o$ holds true,then what type of solution is it?
