Definition

1. Noun:
   • A salt derived by replacing two hydrogen atoms per molecule: A dibasic salt is a chemical compound formed when two hydrogen atoms in an acid molecule are replaced by a metal or other cation. This term is specific to chemistry, describing salts of dibasic acids (acids containing two replaceable hydrogen atoms).

Usage Examples

• Noun:
  • Sodium carbonate is a common example of a dibasic salt.
  • The formation of a dibasic salt requires a reaction with a dibasic acid, such as sulfuric acid.

Advanced Usage

• In chemical nomenclature: The term "dibasic salt" is used to specify the stoichiometry of the salt in relation to its parent acid. It indicates that the salt is neutral, having fully replaced both acidic hydrogen atoms.
  • The laboratory procedure focused on synthesizing the pure dibasic salt from phosphoric acid.

Variants and Related Words

• Dibasic acid (n): An acid that has two replaceable hydrogen atoms per molecule, which can form dibasic salts.
  • Sulfuric acid (H₂SO₄) is a dibasic acid.

Synonyms

• Disalt: A less common synonym indicating a salt where two acidic hydrogens have been replaced.
• Neutral salt (of a dibasic acid): A descriptive synonym emphasizing the salt's lack of acidic hydrogen atoms.

Related Phrases

• Form a dibasic salt: A phrase describing the chemical reaction process.
  • Magnesium will form a dibasic salt with sulfuric acid.
