Web(b) Basic Buffer: It is the mixture of NH 4 OH and NH 4 Cl in aqueous solution. NH 4 OH ⇋ NH 4 + + OH – (incomplete dissociation) NH 4 Cl → NH 4 + + Cl – (complete dissociation) H 2 O ⇋ H + + OH – (incomplete dissociation) Action of acid: when a drop of HCl is added, the added H+ ions combine with NH4OH to form undissociated water ... WebWhen you add HCl to a buffer, there are three possible outcomes: (a) The HCl protonates some, but not all, of the NH 3. You still have a buffer in that case. ... NH 4 Cl ---> 0.225 mol − 0.0750 mol = 0.150 mol Note that NaOH reacts with NH 4 Cl to form NH 3 in a 1:1:1 molar ratio. 4) We are now ready for the Henderson-Hasselbalch Equation:
