Phosphoric Acid (also known as orthophosphoric acid) is a
clear, odorless liquid that may be syrupy depending on the
temperature. Phosphoric acid has many uses including
the production of phosphate fertilizers for agriculture.
Diluted solutions of food-grade phosphoric acid are used to
add a sharp flavor to some soft drinks.
Phosphoric Acid is commonly found in 50% and 85%
concentrated solutions. The 85% solution has a
specific gravity of 1.685. This calls for a 1.9
specific gravity plastic
chemical storage tank. Store
Phosphoric Acid in sealed containers at room temperature and
above its freezing (crystallization) point to maintain
product performance. The storage area should be well
ventilated. Keep away from alkalis, sulfides, cyanides
and metal powders.
Phosphoric Acid is corrosive to Ferrous metals and alloys.
An HDPE tank with PVC fittings and Viton gaskets and O-rings
could be a good Phosphoric Acid storage solution.
