Phosphoric Acid 45%

Phosphoric acid is a highly effective and versatile chemical solution with a wide range of applications across various industries. Its unique properties make it an ideal solution for removing rust, cleaning surfaces, and adjusting pH levels. With its ability to change the reddish-brown iron oxide, phosphoric acid is commonly used to remove rust from iron, steel tools, and other surfaces. Multiple applications may be required to achieve desired results.

In addition to its rust-removing properties, phosphoric acid is also used as a solution for anodising, a buffer agent in biology and chemistry, and as a chemical oxidising agent for activated carbon production. Its uses extend to the production of phosphoric acid fuel cells, oxyhydrogen generators, and as a catalyst in the hydration of alkenes to produce alcohols.

Please see full list below for the various applications Phosphoric Acid 45% is used:

• As a solution for anodising
• As an external standard for phosphorus-31 Nuclear magnetic resonance (NMR).
• As a buffer agent in biology and chemistry; For example, a buffer for high-performance liquid chromatography.
• As a chemical oxidising agent for activated carbon production, as used in the Wentworth Process.
• As the electrolyte in phosphoric acid fuel cells.
• With distilled water (2–3 drops per gallon) as an electrolyte in oxyhydrogen generators.
• As a catalyst in the hydration of alkenes to produce alcohols, predominantly ethanol.
• As an electrolyte in copper electropolishing for burr removal and circuit board planarisation.
• As a flux by hobbyists (such as model railroaders) as an aid to soldering.
• In compound semiconductor processing, phosphoric acid is a common wet etching agent
• Heated in microfabrication to etch silicon nitride (Si3N4). It is highly selective in etching Si3N4 instead of SiO2, silicon dioxide.
• As a cleaner by construction trades to remove mineral deposits, cementitious smears, and hard water stains.
• As a chelant in some household cleaners aimed at similar cleaning tasks.
• In hydroponics pH solutions to lower the pH of nutrient solutions. While other types of acids can be used, phosphorus is a nutrient used by plants, especially during flowering, making phosphoric acid particularly desirable.
• As a pH adjuster in cosmetics and skin-care products.
• As a dispersing agent in detergents and leather treatment.
• As an additive to stabilise acidic aqueous solutions within a wanted and specified pH range.
• As a sanitising agent in the dairy, food, and brewing industries.

Tip:Make sure to work in a well-ventilated area to avoid inhaling the fumes
