Why potassium cannot be obtained by the electrolysis of an aqueous solution of KCI?

Explanation

To understand why potassium cannot be obtained by the electrolysis of an aqueous solution of KCl, we need to analyze the electrochemical processes occurring during the electrolysis. Here’s a step-by-step solution:

### Step 1: Dissociation of KCl in Water
When KCl is dissolved in water, it dissociates into potassium ions (K⁺) and chloride ions (Cl⁻):
\[ \text{KCl (s)} \rightarrow \text{K}^+ (aq) + \text{Cl}^- (aq) \]

### Step 2: Electrolysis Process
During electrolysis, we apply an electric current to the solution, which causes the ions to migrate towards the electrodes. At the cathode (negative electrode), reduction occurs, and at the anode (positive electrode), oxidation occurs.
