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?

In a titration to 5OmL of 0.2M acetic acid (K_(a), = 1.8 xx10^(-5) ),

1.	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?
Answer» Solution :Here , PH `= p^(Ka) , So [S] =[A] ` To GET this, `V_(NAOH),` MUST be 25 ml
