What is the effect of dissolved impurities on freezing point of water

Explanation

### Step-by-Step Solution:

1. **Understanding Freezing Point**: The freezing point of a substance is the temperature at which it changes from a liquid to a solid. For pure water, this is 0°C.

2. **Introduction of Impurities**: When impurities (solutes) are added to water, they disrupt the formation of the solid structure of ice. This means that the water needs to be at a lower temperature to freeze.

3. **Freezing Point Depression**: The phenomenon where the freezing point of a solvent (like water) is lowered by the presence of a solute (impurity) is known as freezing point depression.
