BURNING OF HYDROGEN IN AIR

Hydrogen burns readily in air. A stream of pure hydrogen burn in air quietly with a blue flame. The hydrogen gas is ignited and a beaker of cold water is placed over the flame.Note that hydrogen gas should be passed through the apparatus for sometime to displace air before igniting.

A colourless liquid is collected in a beaker. .

The anhydrous Calcium chloride acts as a drying agent.
