Phosphoric acid

h3po3 h3po4 ph3 Product introduction:

h3po3 h3po4 ph3 oluble in water and alcohol. Pure phosphoric acid is a colorless orthorhombic crystal with high deliquescence. Dissolve in water and ethanol. Its acidity is weaker than strong acids such as sulfuric acid, hydrochloric acid, and nitric acid, but stronger than weak acids such as acetic acid and boric acid. Can irritate the skin, cause inflammation, and damage body tissues. Phosphoric acid dissolves in water and releases heat. When heated at high temperatures, it loses water and forms pyrophosphate and pyrophosphate. When cooled for a long time, it forms crystals, which are corrosive and prone to moisture absorption.

Melting point: 42.35 ℃

Boiling point: 213 ℃

Density: 1.685

Solubility: soluble in water and alcohol

Storage: Sealed storage.

h3po3 h3po4 ph3 Purpose:

To determine the composition of chromium, nickel, and vanadium in steel, metal rust prevention, rubber coagulants, and to measure non protein nitrogen, total cholesterol, and whole blood glucose in serum. Crystalline phosphoric acid is mainly used in manufacturing processes such as microelectronics, high-energy batteries, laser glass, etc., as high-purity catalysts, and medical materials.

Phosphoric acid is mainly used in pharmaceutical, food, fertilizer and other industries, including as rust inhibitor, food additive, dental and orthopaedic surgery, EDIC etchant, electrolyte, flux, dispersant, industrial etchant, fertilizer raw material and component household cleaning products.
