Solution

We can prove that hydrochloric acid contains both hydrogen and chlorine by the following experiment:

On electrolyzing HCl, it is observed that a colourless gas is evolved at cathode and a greenish gas evolved at anode.

When a burning splinter is brought near the colourless gas, it bursts into flame thereby proving that it is hydrogen gas.

When moist starch iodide paper is held in the greenish yellow gas, it turns blue black, thereby proving that the gas is chlorine. The equation for this experiment is:

2HCl→ $H_{2}$ + $C l_{2}$
