What is NaH2PO2? Important knowledge about NaH2PO2.

1. Definition of NaH₂PO₂

NaH₂PO₂, also known as sodium hypophosphite, is a chemical substance in the form of a salt of hypophosphorous acid. Its English name is Sodium Hypophosphite. It consists of the atoms Sodium (Na), Hydrogen (H), and Phosphorus (P). The atomic mass of Na is 23, H is 1, and P is 31. Therefore, the molar mass of NaH₂PO₂ is 105 g/mol. The molecular structure of NaH₂PO₂ includes one sodium atom, two hydrogen atoms, and one phosphorus atom. Its ionic structure is Na+ and H₂PO₂-.

2. Properties of NaH₂PO₂

NaH₂PO₂ is a solid, colorless and odorless substance. It has a neutral PH level. The chemical properties of NaH₂PO₂ relate to its reducing ability, as it reacts with oxygen to form sodium phosphate and water.

3. Common chemical equations involving NaH₂PO₂

The reaction of NaH₂PO₂ with metals, acids, non-metals, and salts is not common.

4. Synthesis of NaH₂PO₂

NaH₂PO₂ is usually synthesized in the laboratory through the dissolution of sodium in hypophosphorous acid. Industrially, NaH₂PO₂ is produced by the reaction of sodium hydroxide with phosphorus to form sodium hypophosphite and water.
