Ph of weak base calculator
Web1 Answer Sorted by: 5 Since 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) WebpH = inf for M solution of weak base with Kb value of. To find pH of a weak base solution, insert concentration (M) and insert Kb value of the weak base (0.001 is input as 1E-3) See …
