Understand process of combustion of hydrogen gas. click on the link toWatch the VIDEO explanation: Watch Video
To prove the property of combustion of hydrogen we need to prepare of hydrogen gas in the laboratory. Zinc granules are taken in a woulf's bottle and the apparatus is arranged as shown here. Dilute Sulphuric acid is dropped into the woulf's bottle through the thistle funnel. Hydrogen gas evolved is pass through U-tube containing calcium chloride. Calcium chloride absorbs the moisture present in Hydrogen. Now what happen when a glowing splinter is brought near the gas coming out through the tube. The gas burns with a pale blue flame with a pop sound. Arrange a setup for circulating cold water. Bring this flame near the flak in which cold water is constantly circulated. Some water droplets are collected at the upper of the flask. This experiment shows that water is formed when hydrogen is burnt in air.
