The role of Water in Showing Alkaline Properties

  1. Alkali shows alkaline properties only in the presence of water.
  2. When water is present, ionisation of alkali produces OH-, ions that are responsible for the alkali properties
  3. Without the presence of water, there are no free-moving hydroxide ions. Therefore, in the absence of, alkalis do not show alkalinity 
  4. Diagram below shows the illustration to investigate the role of water in showing alkaline properties of ammonia.
  5. The ammonia dissolve in water can turn red litmus paper to blue whereas the dry ammonia gas of the ammonia gas dissolve in propanone give no effect to the litmus paper.
