• CH3NH2 → weak base → proton acceptor• H2O → will certainly act as the weak acid → proton donor
Equilibrium reaction: CH3NH2(aq) + H2O(l)⇌ CH3NH3+(aq) + OH-(aq)
Solids and liquids are not included in the expression
Now, we must identify if we have the right to remove (–x) from the equation. To perform so, we need to identify the proportion of the initial concentration and Kb:
