In a titration to 5OmL of 0.2M acetic acid `(K_(a), = 1.8 xx10^(-5) )`, 0.2M of V' mlL of NaOH is added to get a resultant solution of pH=4.74 if V =`x^(2)`?, what is x?

Text Solution

Verified by Experts

The correct Answer is:
5
Here , pH `= p^(Ka) , So [S] =[A] `
To get this, `V_(NaOH) ,` must be 25 ml
