The van’t Hoff factor can be expressed as :

Options

A. the ratio of the freezing-point depression of an electrolyte to that of a non-electrolyte
B. the ratio of the freezing-point depression of a non-electrolyte to that of an electrolyte
C. the number of ions produced by a dissolved solute
D. the ratio of elevation of boiling point of a non-electrolyte to that of an electrolyte

Explanation

To determine how the van't Hoff factor can be expressed, let's break down the problem step by step.

### Step 1: Understand the van't Hoff factor (i)
The van't Hoff factor, denoted as \( i \), is a measure of the number of particles a solute produces in solution. It is particularly important for electrolytes, which dissociate into ions.

### Step 2: Define the van't Hoff factor mathematically
The van't Hoff factor can be mathematically defined as:
\[
