acidification

The ocean's acidification harms coral reefs.

Definition

Noun: * The process of becoming acid or being converted into an acid: A chemical process where the acidity of a substance increases, meaning its pH level decreases. This often refers to the ongoing decrease in the pH of the Earth's oceans, primarily due to the absorption of atmospheric carbon dioxide (CO₂).

Usage
  • Acidification is an uncountable noun used to describe a gradual, large-scale chemical process.
  • It is commonly used in environmental science, chemistry, and oceanography.
  • Typical sentence patterns: "the acidification of [something]", "ocean/sea acidification", "leads to/causes acidification".
Examples
  • Environmental Context:
    • Ocean acidification is a major threat to marine ecosystems like coral reefs.
    • Scientists are studying the effects of acidification on shellfish populations.
  • General/Chemical Context:
    • The acidification of the soil made it unsuitable for growing those plants.
    • This chemical reaction results in the acidification of the solution.
Advanced Usage
  • "Runaway acidification": A scenario where the acidification process accelerates and becomes self-reinforcing or very difficult to reverse.
  • "Acidification potential": A measure used in environmental science to estimate the capacity of a substance to contribute to acidification.
Variants and Related Words
  • Acidify (verb): To make or become acid.
    • Carbon dioxide dissolves in seawater and acidifies it.
  • Acid (noun/adjective): The chemical substance or property involved in the process.
  • Deacidification (noun): The process of removing or neutralizing acid (the opposite process).
Synonyms
  • Acidulation (a more technical/archaic term, often for a deliberate process).
  • Lowering of pH (a descriptive phrase rather than a direct synonym).
Related Phrases
  • "Buffer against acidification": To have a chemical resistance or capacity to reduce the impact of acidification.
    • Some minerals in the water can buffer against acidification.
  • "Rate of acidification": The speed at which the acidification process is occurring.
    • The rate of acidification in the Arctic Ocean is particularly high.
