Question

Is water an Arrhenius base?


Open in App
Solution

Water is neutral.

Arrhenius theory of base: A chemical known as an alkali dissolves in an aqueous solution and ionizes into an OH- ion. The solution contains a significant amount of OH- ions.

  1. The number of hydrogen ions (H+) released determines the strength of an Arrhenius acid, and the amount of released hydroxide ions (OH) determines the strength of an Arrhenius base.
  2. The more H+, the more the pH will drop as the ions are released, making the acid stronger.
  3. The higher the OH content higher the pH values ​​and stronger bases result in discharged ions.
  4. However, on the pH scale, water is a neutral molecule.
  5. The pH scale allows the contrast of various acids and bases concerning water, which has a pH of 7.
  6. Dissociation with water produces both H+ and OH-.
  7. H2OH++OH
  8. According to Arrhenius's theory, water is a neutral chemical.
  9. pH value range of water on temperature change.
