Consider the titration of 100.0 ml of 0.010 0 m ce in i m hcio, by 0.040 0 m cu' to give ce and cu, using pt and saturated ag | agcl electrodes to find the end poin. (a) write a balanced titration reaction. (b) write two different half-reactions for the indicator electrode. (c) write two different nernst equations for the cell voltage. (d) calculate e at the following volumes of cu: 1.00, 12.5, 24s 25.0, 25.5, 30.0, and 50.0 ml. sketch the titration curve.

What happens to the atomic radius when an elctron is lost

)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.
