Frequent Uses

Catalyst in Organic Reactions

It acts as a catalyst in the hydration of alkenes, such as the conversion of ethene to ethanol. This is a significant process in organic chemistry for producing alcohols.

Cleaning and Maintenance of Laboratory Equipment

Commonly used removing mineral deposits, such as calcium carbonate and other hard water residues, from laboratory glassware. It can dissolve lime scale and other inorganic residues that accumulate during chemical reactions or through the use of hard water.

Preparation of Buffer Solutions

Used to prepare buffer solutions in laboratories. These buffers are essential in biological and chemical experiments, as they help to maintain a stable pH, particularly in the pH range of 5 to 7. It is often used in conjunction with sodium or potassium phosphates to create phosphate buffers.

Surface Treatment and Etching

In electrochemical processes, Phosphoric Acid is used as an electrolyte solution in anodising, primarily for aluminum, to increase corrosion resistance and improve surface hardness.
