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

Options

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

Answer

A

Explanation

Dissociation constant for :
`HA hArr H^(+) +A^(-)`
Can be given as :
`K_(s)=([H^(+)][A^(-)])/([HA])`
Therefore, we can say that dissociation constant is a measure of its ability to furnish proteons in the solution.
