This increnscs the cxtcnt of clissocintion in the original solution: if K. is much lnrgcr than Ifto\* the incrcrrsc will bc so cxtcnsivc that the titration curve will assume the form of that for II "strong" (i.c., cswntially complctcly clissociatccl) acid. If ICo is comparable to or smollcr than I<,
