In this experiment we will determine the equivalent weight of Iron, which displaces one equivalent of copper (63.5 g) from a solution containing copper ions.
Procedure: Clean a sample of iron (strip measuring 3.5cm×1.5cm) with a sand paper and weigh it accurately. Place it in a clean beaker (250ml) and pour into it 100ml of CuSo4 solution of known strength (~ N/10) Allow the strip to stand in the beacker for about 30 minutes. Carefully withdraw the strip of iron (from the beaker) with a forceps and place it on a porcelain plate contained in a desiccafor (using cacl2 as a desiccant ). The quantity of copper sulphate remaining in solution – after the chemical displacement, is estimated by lodometric titration method. The dried strip of iron (containing the deposited copper) is then carefully weighed.
Observations:
Weight of iron strip = …………….g
Wt. Of iron strip + copper = ………………g
(after drying )
wt. of copper deposited on iron strip Þ
Initial conc. of cu- final conc. of cu. (determined by titration)
The weight of iron, which goes into solution(as Fe So 4)
Þ ( Initial weight of iron strip + weight of deposited copper) - weight of iron strip along with copper (after drying)
Eq.wt. of copper (63.5) = Wt. of Copper Deposited
Eq. Wt. of Iron Wt. of Fe(s) (going into solution)
The Eq. Wt. of Fe = ?
The % error involved in the experiment =……………….
