When dilute hydrochloric acid is added to granulated zinc placed in a test tube, the observation made is:
(1) the surface of the metal turns shining. | (2)the reaction mixture turns milky. |
(3)odour of chlorine is observed. | (4)a colourless and odourless gas evolves with bubbles. |
Correct answer: (4) a colourless and odourless gas evolves with bubbles.
Explanation: When dilute hydrochloric acid is added to granulated zinc, hydrogen gas is produced, which is a colourless and odourless gas and is evolved with bubbles.
The chemical equation for the reaction is given below:
$2HCl(l)+Zn(s)→ZnCl_2(aq)+H_2(g)$
