Water will tend to flow in the direction from B to A until equilibrium is reached. As we know AlCl3 is ionic compond where ethyl alcohal has very less ionic character thus water will tend to flow in direction where it can interact with Al3+ and forms a complex where Al is surrounded by 6 O atoms and Cl by H, Thus stablishing the solution wheras in ethyl alcohal there is very less ionic character thus water wont prefer itself on side B.
