WebbCalculate the pH of a buffer solution that initially consists of 0.0500 M NH 3 and 0.0350 M NH 4+. (Note: K a for NH 4+ is 5.6 x 10 -10 ). The equation for the reaction is as follows: \text {NH}_4^+ \rightleftharpoons \text {H}^+ + \text {NH}_3 NH4+ ⇌ H+ +NH3 We know that initially there is 0.0350 M NH 4+ and 0.0500 M NH 3. WebbSince p K a + p K b = 14, you get p K a = 10.64 for the methylammonium cation. H C l protonates methylamine. The amount of methylammonium increases by the same amount methylamine decreases. So. p K a = p H + log ( [ H A] [ A X −]) = p H + log ( x 10 m m o l − x) lets you calculate the value x of H C l needed to obtain the desired p H.
