Assertion : It is difficult to distinguish the strengths of the strong acids such as

                  HCl, H2SO4, HNO3, HBr, Hl or HClO4 in dilute aqueous solutions.

Reason : In dilute aqueous solution all strong acids donate a proton to water and are essentially.

               100% ionised to produce a solution containing H3O+ ions plus the anions of strong acid.

  1. If both the assertion and the reason are true and the reason is a correct explanation of the assertion
  2. If both the assertion and reason are true but the reason is not a correct explanation of the assertion
  3. If the assertion is true but the reason is false
  4. If both the assertion and reason are false
