Why is the pH>7 if its acidic in the first place.
Secondly, shouldnt we just consider [H+] to be dominated by water?
It's just called acidic buffer coz it's a buffer of an acid and it's salt. Doesn't mean pH has to be less than 7 bro.
And no we can't neglect H+ because it's concentration is very high here.
It is acidic buffer form with NACN and HCN.The name "acidic" is does not mean the solution is acidic.However as per the given molarity we can easily understand that concentration of (H+) is very high which can not be neglect.
