Question

What are the effect of impurities present in water on the melting point and boiling point of water?

Answer 1

The effect of impurities present in water on the melting point of water:

• The presence of impurities in water decreases the melting point of water.
• Because impurities in water results in melting point depression.

The effect of impurities present in water on the boiling point of water:

• The presence of impurities in water increases the boiling point of water.
• Water molecules available for vaporization decreases because of impurities in water.
• The heat required for vaporizing the impure water solution is more than the heat requires for vaporizing the pure water solution
