When lead sulphate is added to an aqueous solution of sodium iodide, the fclioWing equilibrium is obtained. PbSO(s) + 21 (aq) Pbl2(s) + So, (aq)- The equilibrium constant for this reaction may be determined by adding an excess of lead sulphate to a known volume of a standard solution of sodium iodide and allowing the mixture to equilibrate in a water bath, thermostatically controlled at ihe desired temperature. Cold water is then added to the reaction mixture to "freeze" the equilibrium and the mixture is then titrated with standard silver nitrate solution. In a typical experiment using 50 cm of 0.1M sodium iodide a titre of 31.0 cm of 0.1M silver nitrate was obtained.

For a 50ml beaker, 0.4532g of pure iron III oxide was weighed, to which 1 ml of a concentrated hydrochloric acid solution was added and then 20 ml of deionized water was added to the beaker. After mixing, the resulting solution was transferred to a 50.00 ml flask and the volume was made up with deionized water. Then 15ml of this solution into a second beaker to which 10ml of an iron iii chloride solution of 0.200 M concentration was added. Calculate the final concentration of the iron iii cation solution expressed in mol/L and in g/L, considering that the volumes are additive.
