Which cation in the given pair will be discharged first during electrolysis under similar conditions ?
`Na^(+) and Mg^(2+)`

Explanation

To determine which cation, Na⁺ or Mg²⁺, will be discharged first during electrolysis under similar conditions, we can follow these steps:

### Step 1: Understand the Process of Electrolysis
During electrolysis, cations (positively charged ions) move towards the cathode (the negatively charged electrode) where they gain electrons and undergo reduction.

### Step 2: Identify the Cations
The cations given are:
- Sodium ion (Na⁺)
