How many moles of copper will be displaced when 2 mol of copper sulphate is treated with iron
Answers
Explanation:
When zinc reacts with a solution of copper sulphate, we obtain Zinc Sulphate and Copper.
Zn + CuSO
4
→ ZnSO
4
+ Cu
Zinc lies above Copper in the activity series.The activity series of metals refers to the list of metals ranked in the decreasing order of their reactivity in order to displace Hydrogen gas from water or acid solutions
Iron metal is more reactive than copper. Therefore, it can displace copper from copper sulphate solution. Cu is less reactive than iron, therefore, cannot replace iron from iron sulphate.
Fe + CuSO
4
→ FeSO
4
+ Cu
The metallic copper produced will be weighed. These weighings will be used to calculate the moles of iron used and the moles of copper formed. If equation (1) is correct, the moles of copper should equal the moles of iron. If equation (2) is correct, we should obtain 1.5 moles of copper per mole of iron.
