Understand Hydrogen is lighter than air. click on the link to Watch the VIDEO explanation: Watch Video
To prove that Hydrogen is Lighter than Air we need to prepare to hydrogen gas in the laboratory. Zinc granules are taken in the woulf's bottle and the apparatus is arranged shown here. Dilute Sulphuric acid is dropped into woulf's bottle through the thistle funnel. The hydrogen gas formed is made to pass through the caustic soda solution so that it becomes free form acid and the gas is passed through the soap solution taken the trough. What you observe. You will find that the bubble of hydrogen formed rise upward like balloons. This shows the gas present in bubbles is lighter than air.
