Unless otherwise specified, assume infinite dilution (i. e., activity coefficient = 1). 1. several different forms of chlorine can be used to disinfect water. in particular, it can be added as bleaching powder (ca(oci)2), bleach (naoci) or as cl2 (which dissolves in water to form hoci). predict the ph of a 1 x 10* m solution of chlorine if it is added to pure water: a. as hoci? (solve without making any simplifications] as naoci? (solve without making any simplifications] c. repeat your calculation for part (a) using a simplifying assumption that the equilibrium ph is much less than the pka of hoci. how much error does this introduce into your answer?

)benzene and toluene form nearly ideal solutions. consider an equimolar solution of benzene and toluene. at 20 °c the vapour pressures of pure benzene and toluene are 9.9 kpa and 2.9 kpa, respectively. the solution is boiled by reducing the external pressure below the vapour pressure. calculate (i) the pressure when boiling begins, (ii) the composition of each component in the vapour, and (iii) the vapour pressure when only a few drops of liquid remain. assume that the rate of vaporization is low enough for the temperature to remain constant at 20 °c.
