Properties
and storage:
Hydrochloric acid (sometimes called muriatic acid)
is a concentrated solution of hydrogen chloride
gas in water. When exposed to air, it fumes freely.
These fumes are irritating to the skin.
The
commercial product may have a light yellow colour
due to the presence of iron, free chlorine and
organic matter. As hydrochloric acid attacks most
metals and a number of alloys, it has to be stored
either in glass, polythene carboys or in rubber-lined
or PVC-lined tanks.
Uses: Hydrochloric acid is used in the
production of chlorides for picking of iron during
its pre-treatment in the galvanising and tinning
processes. It can also be used in the manufacture
or organic hydrochloric acid and in de-scaling
boilers and other evaporating equipment.
Packing:
HM / HDPE carboys; five-tonne (approximately)
truck tanker.
