hydrolith

A scientist carefully handles a hydrolith sample in the laboratory.

Definition

Noun: 1. A chemical compound: Specifically, a binary, salt-like inorganic compound with the chemical formula CaH₂. It is primarily used as a powerful reducing agent in chemical processes and as a portable, solid source of hydrogen gas.

Usage
  • Hydrolith is a technical term used almost exclusively in chemistry and industrial contexts. It refers to the specific compound calcium hydride.
  • It functions as a noun, typically as the subject or object in a sentence describing a chemical reaction or process.
Examples
  • The laboratory used hydrolith to dry organic solvents by reacting with any trace water.
  • When hydrolith comes into contact with water, it produces hydrogen gas.
  • For the synthesis, we needed a strong reducing agent, so we chose hydrolith.
Advanced Usage
  • As a desiccant: In advanced laboratory work, hydrolith is valued not just as a hydrogen source but as an extremely effective drying agent for gases and solvents.
  • In metallurgy: Hydrolith can be used to reduce metal oxides to their pure metallic forms at high temperatures.
Variants and Related Words
  • Calcium hydride: This is the systematic IUPAC name and a direct synonym for hydrolith. It is the more commonly used term in modern scientific literature.
  • Reducing agent: A general term for a substance that donates electrons in a chemical reaction; this describes one of the primary functions of hydrolith.
  • Desiccant: A substance that absorbs moisture; this describes another key use of hydrolith.
Synonyms
  • Calcium hydride (n): The systematic chemical name; interchangeable with hydrolith.
  • CaH₂ (n): The chemical formula, used as shorthand in equations and technical notes.
Notes on Meaning
  • The term hydrolith is largely historical or specialized. In most contemporary chemistry texts and discussions, the compound is referred to by its systematic name, calcium hydride.
  • Its defining characteristics are its composition (calcium and hydrogen), its ionic, salt-like structure, and its vigorous, exothermic reaction with water to yield hydrogen gas (H₂).
