Question

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

• A. If both Assertion and Reason are true and Reason is the correct explanation of Assertion
• B. If both Assertion and Reason are true but Reason is not the correct explanation of Assertion
• C. If Assertion is true but Reason is false
• D. If Assertion is false but Reason is true

Answer 1

Answer: (A)

Dissociation consant for :

$HA \, {\leftrightharpoons}\, H^{+} + A^{-}$

Can be given as :

$K_{s} = \frac{\left[H^{+}\right]\left[A^{-}\right]}{\left[HA\right]}$

Therefore, we can say that dissociation constant is a measure of its ability to furnish protons in the solution.
