Ammonia in window cleaners is basic in nature; it is a base/alkali.

Why we say ammonia is basic

  • Ammonia solution in water (often called ammonium hydroxide) turns red litmus paper blue, which is the standard test for a base.
  • Bases have a pH greater than 7, and household ammonia solutions are typically strongly alkaline.
  • In cleaners, this basic nature helps dissolve grease, oils, and other organic residues, making it an effective cleaning agent.

So, when the question says “ammonia is found in many household products such as window cleaner, what is its nature?”, the expected answer is: It is basic (alkaline) in nature.
