• A. $\text{A}:\text{Cathode}$
  $\text{B}:\text{Anode mud}$
  $\text{C}:\text{Anode}$
  $\text{D}:\text{Electrolyte}$
• B. $\text{A}:\text{Anode}$
  $\text{B}:\text{Cathode}$
  $\text{C}:\text{Anode mud}$
  $\text{D}:\text{Electrolyte}$
• C. $\text{A}:\text{Cathode}$
  $\text{B}:\text{Cathode mud}$
  $\text{C}:\text{Electrolyte}$
  $\text{D}:\text{Anode}$
• D. $\text{A}:\text{Anode}$
  $\text{B}:\text{Anode mud}$
  $\text{C}:\text{Electrolyte}$
  $\text{D}:\text{Cathode}$

Answer 1

The correct option is D $\text{A}:\text{Anode}$

$\text{B}:\text{Anode mud}$
$\text{C}:\text{Electrolyte}$
$\text{D}:\text{Cathode}$
The process of electrolysis consists of an anode and a cathode dipped in an electrolyte solution and connected together to a battery.

• Anode is the electrode connected to the positive terminal of the battery $(+)$.
• Cathode is the electrode connected to the negative terminal of the battery $(-)$.
• As the electric current is passed through the electrodes, the impure anode starts to disintegrate leaving anode mud as a residue.

Therefore, the parts labelled in the given case of electrolysis are:
$\text{A}:\text{Anode}$
$\text{B}:\text{Anode mud}$
$\text{C}:\text{Electrolyte}$
$\text{D}:\text{Cathode}$
