Draw a neat and labelled diagram to show the following activity:

Action of Dil H₂SO₄ on Zn granules.
(i) Name the gas evolved.
(ii) How will you test for the gas?

(i) Hydrogen gas is evolved in this process. 

(ii) The equation for the above reaction is given below:

 $Zn( s) \ +\ H_{2} SO_{4}( aq)\rightarrow \ ZnSO_{4\ } +\ H_{2} \uparrow $

Test for H₂ gas: The presence of Hydrogen gas can be tested by passing the gas through soap solution and then bringing a burning splinter near the soap bubbles filled with the gas. If the gas burns with a pop sound, it is hydrogen.
