Dissolving Hydrogen Chloride - Inverted Funnel.
Hydrogen
chloride gas is so soluble that
it can dissolve in the water
more quickly than it comes from the supply.
The decrease in pressure in the supply tube causes water
to be sucked
back up the tube!
The safe
method for dissolving any
gas of high
solubility
is to use an inverted funnel
(funnel turned upside down) as
shown.
As the dissolved gas causes
water to be sucked back up the tube,
the large volume of the funnel
causes the water level to drop.
When the water level drops below the mouth
of the funnel,
all the water in the funnel runs back into
the container.
Hydrogen chloride dissolves in water to form hydrochloric acid.
