Van't Hoff Factor Calculator

Formula

The formula to calculate the Van't Hoff Factor is:

\[ i = a \cdot n + (1 - a) \]

Where:

\( i \) is the Van't Hoff Factor
\( a \) is the degree of dissociation
\( n \) is the number of ions formed from one formula unit of the substance

What is the Van't Hoff Factor?

The Van't Hoff Factor is the ratio of the actual concentration of particles produced when a substance is dissolved to the concentration of the substance as calculated from its mass. It indicates the effect of solute particles on colligative properties such as boiling point elevation, freezing point depression, and osmotic pressure.

Example Calculation

Let's assume the following values:

Degree of Dissociation (\( a \)) = 0.8
Number of Ions Formed (\( n \)) = 3

Using the formula to calculate the Van't Hoff Factor:

\[ i = (0.8 \cdot 3) + (1 - 0.8) = 2.4 + 0.2 = 2.6 \]

The Van't Hoff Factor is 2.6.
