a)C2H5OH will have lowest ellectricalconductivity because it will not form ions in solutions.
b)MgCl2 has lowest freezing point because insolution MgCl2 gives more no. of particles.
c)C2H5OH has the highest vapour pressurebecause ethano will form less no. of particles in solution.
d)MgCl2 addition will shift the equilibrium H2OH++OH because theformed Cl will consume the H+ ions therebydecreasing its conc. which effectively increases OH concentration and pH.
