Complete the following reaction
`KCl overset"electric current"to`

Explanation

To complete the reaction of KCl when electric current is passed through it, we follow these steps:

### Step-by-Step Solution:

1. **Identify the Substance**: We start with potassium chloride (KCl).

2. **Understand Electrolysis**: When electric current is passed through KCl, we are performing a process called electrolysis. Electrolysis involves breaking down a compound into its constituent ions using electric current.
