Van't Hoff factor, i for KCl is .........

Explanation

To find the Van't Hoff factor (i) for KCl, we need to follow these steps:

### Step 1: Understand the concept of Van't Hoff factor
The Van't Hoff factor (i) is a measure of the number of particles a solute breaks into when it dissolves in a solvent. For ionic compounds, this factor is determined by the number of ions produced when the compound dissociates in solution.

**Hint:** Remember that ionic compounds dissociate into their constituent ions in solution.

### Step 2: Identify the dissociation of KCl
