`HNO_3`(aq) is titrated with NaOH(aq) condutomatrically, graphical representation of the titration is :

Options

A.
B.
C.
D.

Answer

A

Explanation

Molar conductivity of `H^(-)` and `OH^(-)` are very high as compare to other ions .
Initially conductance of solution sharply decreases due to consumption of free `H^(+)`. After complete neutralization further slightly increases due to presence of `OH^(-)`
