Solution - How would you confirm that a colourless liquid given to you is pure water? - CBSE Class 9 - Science

ConceptSeparate a Mixture of Two Miscible Liquids

Question

How would you confirm that a colourless liquid given to you is pure water?

Solution

Every liquid has a characteristic boiling point. Pure water has a boiling point of 100°C (373 K) at 1 atmospheric pressure. If the given colourless liquid boils at even slightly above or below 100°C, then the given liquid is not pure water. It must boil at sharp 100°C. Thus, by observing the boiling point, we can confirm whether a given colourless liquid is pure water or not.

Is there an error in this question or solution?
