Assertion : Relative strength of acids can be known by knowing the value of dissociation constant. Reason : It gives the value of H+\mathrm{H}^{+}dissolved in solution.

Options

  1. AIf both Assertion and Reason are true and Reason is the correct explanation of Assertion.
  2. BIf both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
  3. CIf Assertion is true but Reason is false.
  4. DIf Assertion is false but Reason is true.

Correct answer

A. If both Assertion and Reason are true and Reason is the correct explanation of Assertion.

Step-by-step solution

Dissociation consant for : H\mathrm{H}A ⇌H++\rightleftharpoons \mathrm{H}^{+}+A^{-} Can be given as : K_s=[H+][A−][HA]\frac{\left[\mathrm{H}^{+}\right]\left[A^{-}\right]}{[\mathrm{H} A]}Therefore, we can say that dissociation constant is a measure of its ability to furnish protons in the solution.
