Explanation

To solve the question, we need to fill in the blank with the appropriate word or phrase from the options provided. The sentence we need to complete is:

"The cations on reaching ______ gain electrons and form neutral atoms which get deposited on the cathode."

### Step-by-Step Solution:

1. **Identify the Role of Cations:**
- Cations are positively charged ions. In electrochemistry, they migrate towards the cathode during electrolysis.
