(b) Surface sanitizers were prepared using ethyl alcohol/water and isopropyl alcohol water solutions. An experiment was done to determine which composition would be most effective and as such two solutions were formulated: 70 % v/v ethyl alcohol and 70 % v/v isopropyl alcohol. Calculate the vapour pressure of these solutions and use your answer to reason which combination would stay on the surface longer. (10 marks) Pº (Ethyl alcohol) = 12.4 kPa Pº (Isopropyl alcohol) = 4.4 kPa Pº (Water) = 2.4 kPa
