Question

e) i) Here is an electrode reaction:
[5]
Cu-Cu +2 +2e
At which electrode (anode or cathode) would such a reaction take place? Is this an
example of oxidation or reduction?
A solution contains magnesium ions (Mg+),iron (II) ions (Fe+2) and copper ions
(Cut?). On passing an electric current through this solution which ions will be the
first to be discharged at the cathode? Write the equation for the cathode reaction?
iii)
Why is carbon tetrachloride, which is a liquid, a non- electrolyte?​

Answer 1

Answer:

a) The reaction takes place at anode. This is an example of oxidation.

(b) Cu+2 will discharge easily at cathode.

Reaction at cathode:

Cu+2 +2e- ⟶ Cu

(c) Carbon tetrachloride is a non-electrolyte because it is a covalent compound. It does not ionize and hence do not conduct electricity
