phosphite

A chemist adds phosphite to a solution in a laboratory.

Definition
  1. Noun:
    • A salt or ester of phosphorous acid: In chemistry, "phosphite" refers to a compound derived from phosphorous acid (H₃PO₃) by replacing one or more of its hydrogen atoms with a metal or organic group.
    • A reducing agent: "Phosphite" is also used to describe a type of chemical that can donate electrons in chemical reactions, often used in industrial processes or as a fertilizer.
Usage Examples
  • Noun:
    • The chemist synthesized a new phosphite compound for use in flame retardants. (A salt or ester of phosphorous acid created in the lab.)
    • Phosphite fertilizers are often applied to crops to improve resistance to disease. (A chemical substance used in agriculture to boost plant health.)
Advanced Usage

  • "Phosphite ion": The specific negatively charged particle (PO₃³⁻) derived from phosphorous acid.

    • In solution, the phosphite ion can act as a mild reducing agent. (The ion participates in oxidation-reduction reactions.)

  • "Phosphite ester": An organic compound where the hydrogen of phosphorous acid is replaced by an alkyl or aryl group.

    • Certain phosphite esters are used as stabilizers in plastics. (Organic derivatives of phosphorous acid.)
Variants and Related Words

    • Phosphorous acid is the parent compound of phosphites. (The acid from which phosphites are derived.)

  • Phosphate (n): a salt or ester of phosphoric acid (H₃PO₄), which is chemically similar but more oxidized than phosphite.

    • Unlike phosphite, phosphate is a common component of DNA. (A related but distinct chemical compound.)
Synonyms
  • Hypophosphite: a salt or ester of hypophosphorous acid (H₃PO₂), which is even less oxidized than phosphite.
