Question

How can we check the purity of solids?

Answer 1

Answer:

Pure solids:

• The pure solids have a fixed melting point at a constant pressure.
• Hence we can check the purity of a solid by measuring its melting point.
• If a solid is impure it means it contains some other substances and due to these other substances the melting and boiling point of that solid will change.

Conclusion:

Therefore, we can check the purity of a solid by measuring its melting point.
