Definition

  1. Verb (transitive):

    • To make a substance alkaline; to increase the pH level of a substance, making it less acidic and more basic.

  2. Verb (intransitive):

    • To become alkaline; for a substance to undergo a chemical change resulting in a higher pH level.
Usage
  • As a transitive verb, "alkalinise" takes a direct object (the substance being changed).
  • As an intransitive verb, it describes the process a substance undergoes.
  • This term is primarily used in scientific, medical, and industrial contexts.
Examples

  • Transitive Verb:

    • Farmers sometimes alkalinise the soil by adding lime to counteract excessive acidity.
    • The lab technician was instructed to alkalinise the solution before adding the next reagent.

  • Intransitive Verb:

Advanced Usage
  • "Alkalinise" vs. "Alkalize": "Alkalinise" is the preferred spelling in British English, while "Alkalize" is more common in American English. Both have identical meanings.
  • In Medical Contexts: The term can describe therapeutic interventions, such as giving a patient bicarbonate to their urine.

  1. make (a substance) alkaline
