WebThe presence of this gas can be proved using the limewater test. Teaching notes. It advisable to try the fountain experiment before demonstrating it to a class, to make sure the flask can be successfully filled with HCl gas. Be careful not to disconnect the flask from the gas supply too soon, even if HCl can be detected at the outlet. WebHydrogen Chloride (HCl) is a colourless gas with an irritating pungent odour detectable at ~0.8 ppm. It is very soluble in water (673 g L-1 at 30°C) (Gangolli, 1999) and reacts in moist air to form a mist. It is non-flammable in air and has a density of 1.49 g L-1 at 25°C and 1 atm (Lide, 2003), 1.2 times that of ambient air.
