In case you did not know, the part of the salt from the weak acid removes some of the H+ ions from the water equilibrium causing changes in this equilibrium that result in [OH-] increasing. It commonly ranges between 0 and 14, but can go beyond these values if sufficiently acidic/basic. For CH3NH3Cl, we know that Cl- is the conjugate base of HCl (a strong acid), which means that Cl- has no affect on the pH.
