Phosphoric (V) Acid ( Ortophsphoric ) 85% - 500ml

PHOSPHORIC ACID 85%

Chemical Formula: H3PO4
Molar Mass: 98.00 g/mol
CAS Number: 7664-38-2

Phosphoric acid 85% is a concentrated aqueous solution of phosphoric acid. It appears as a colorless, syrupy liquid that is highly soluble in water. The 85% concentration indicates that the solution contains 85% phosphoric acid by weight, with the remaining 15% being water.

Applications:

1. Chemical Industry: Phosphoric acid is widely used as a precursor for the production of phosphate salts and fertilizers. It serves as a reagent in various chemical reactions and as a pH adjuster in industrial processes.
2. Metal Treatment: In metalworking, phosphoric acid is used for rust removal and surface preparation, as it reacts with rust (iron oxide) to form a water-soluble compound. It is also employed in phosphating processes to provide a corrosion-resistant layer on metal surfaces.
3. Industrial Cleaning: Phosphoric acid 85% is a common ingredient in industrial cleaning agents, particularly for removing mineral deposits, scale, and stains from equipment, machinery, and surfaces.
4. Electronics and Semiconductor Industry: It is used in the etching and cleaning of semiconductor materials during manufacturing.
5. Catalysis: Phosphoric acid is utilized as a catalyst in some chemical synthesis processes, including the dehydration of alcohols.

Phosphoric acid 85% is corrosive and can cause severe burns to the skin, eyes, and respiratory system. Proper handling procedures should include the use of personal protective equipment (PPE), such as gloves, goggles, and chemical-resistant clothing. It should be stored in a tightly sealed container made of compatible materials, such as plastic or glass, in a cool, dry, and well-ventilated area away from incompatible substances like strong bases and reactive metals.
