Strength of Alkalis

  1. Similar to strength of acids, the strength of an alkali is defined by its ability to ionise and release hydroxide ions (OH-) in the solution.
  2. In a solution of strong alkali, all the alkali molecules are ionised in the water to produce hydroxide  ions.
  3. In a solution of weak alkali, only small portion of the molecules are ionised to release hydroxide ions.
  4. Table below shows some example of strong/weak alkalis.
