Is a weak acid-weak base titration profile possible?why or why not?
The tiration curve for the neutralization of a weak acid by a weak base has three complications : 1) in the acidic region , the pH tends to be kept constant by an HX/X- buffer 2) in the basic region , the pH tends to be kept constant by a BOH/ B+ buffer 3) at the equivalence point , there is an extensive hydrolysis of the equivalent salt , which may in some cases lead to a neutral ( pH =7) or near neutral solution.
