Answer 1

Answer:

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

Answer 2

Pure water is obtained by fractional distillation. It has only water molecules. By this we conclude purity of water.
