Answer:

How would you confirm that a colourless liquid given to you is pure water? A very easy solution is to take a sample of the colourless liquid and put it on the stove if it starts boiling exactly at 100 ºC then it is pure water. Any other colourless liquid such as vinegar always has a different boiling point.
