A solution contains 1.694 g of cobalt sulphateCoSO4per litre.Calculate: (1.5)a) the volume of 0.008640 M EDTA solution requiredto titrate 25.0 mLof the cobalt solution. b) the volume of a0.009450 M Zn solution required for titrating the excess of EDTA if50.00 mL of the 0.008640 M EDTA solution had previously been addedto 25.00 mL of the initial solution. c) the volume of 0.008640 MEDTA solution required to titrate Zn2+being displaced by Co2+afterthe addition of an excess of ZnY2-to 25.00 mL of the CoSO4solution.
