Electrolysis
State one relevant observation for the following:
At the anode when aqueous copper sulphate solution is electrolyzed using copper electrodes.
Nothing is left at the anode as copper atoms form copper ions and migrate towards the cathode.

Give appropriate scientific reason for the following statement:
During electrolysis of molten lead bromide, graphite anode is preferred to other electrodes.
Graphite is an inert electrode which is preferred in the electrolysis of molten lead bromide because if other active electrodes are used then bromine will react with them.
The electrical conductivity of acetic acid is less in comparison to the electrical conductivity of dilute sulphuric acid at a given concentration ?
Acetic acid is a weak acid and has fewer number ions so conductivity is less whereas dilute Sulphuric acid is a strong acid has more number of ions and therefore its electrical conductivity is more.
Electrolysis of molten lead bromide is considered to be a redox reaction.
During electrolysis of molten lead bromide lead gets oxidised and bromine gets reduced. Thus both oxidation and reduction occur simultaneously. So it is a redox reaction.
