In wikipedia puts that is done by the reaction of the hydrochloric acid with sulphur férroso FeS. But the result is in gaseous state not in liquid.
Any form to do it Liquid?

Bubble the gas through water with a gas-generating apparatus easily made from a flask, thistle funnel, pinchcock, and glass tubing. Make sure to use
diluted HCl as some HCl fumes will carry over if you use concentrated. Then you will have a solution of 'hydrosulfuric acid'. Do this in a fume hood
or outside with some sort of gas mask effective against H<sub>2</sub>S because it is an insidious poison (it numbs your olfactory nerve).
