buffer - Answer A buffer is an aqueous solution containing a weak acid and its conjugate base
or a weak base and its conjugate acid
-minimizes change in pH when OH- or H+ added
-WA will consume added OH- (NH4)
-WB will consume added H+ (NH3)
pH<pKa - Answer more acid in solution
pH=pKa - Answer at equilibrium
pH>pKa - Answer more base in solution
