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


Answer :

We can confirm that if a colourless liquid is pure by boiling it. If the colourless liquid boils at 100°C and then leaves no residues then it is said to be pure. But if there is result left in the container and there is a decrease or increase in the boiling point of that residue, then it is impure.
