Question

A student took 10ml of Hcl in a conical flask and added a few pieces of Zinc metal. Name the gas
evolved and write one property of the gas evolved.

Answer 1

Hi!!

Your answer is:

When zinc metal is added to Hydrochloric acid, zinc chloride is formed with the liberation of Hydrogen gas.

Zn + 2HCl ----------> ZnCl2 + H2(g)

When the mouth of the flask is brought near a burning matchstick after the reaction, the gas burns with a pop sound.

Hope it helps!!

Answer 2

H2 gas i.e. hydrogen is evolved. H2 burns with a pop sound.
