Why is depression of freezing point of 0.1 M sodium chloride solution nearly twice that of 0.1 M glucose solution?

Explanation

To understand why the depression of freezing point of a 0.1 M sodium chloride (NaCl) solution is nearly twice that of a 0.1 M glucose solution, we can break it down into steps:

### Step 1: Understand the nature of the solutes
- Sodium chloride (NaCl) is an electrolyte, meaning it dissociates into ions when dissolved in water. Specifically, it dissociates into Na⁺ and Cl⁻ ions.
- Glucose, on the other hand, is a non-electrolyte and does not dissociate into ions in solution.

### Step 2: Determine the van 't Hoff factor (i)
- For NaCl, when it dissociates, it produces two particles (Na⁺ and Cl⁻). Therefore, the van 't Hoff factor (i) for NaCl is 2.
