(Please explain method step by step, this is a redox reaction)

Solutions

Expert Solution

We have the ionic redox equation as:

half reaction are written as

At anode

At Cathode

Now eqn (i) will be multiplied by 3 and eqn (ii) will be multiplied by 7, we have become

Now add equation(iii) and equation(iv), we get

Answer.
