Determine the pH of each solution:

(a) 0.10 M NH4Cl

can someone show me how to do this one so i have the idea of how to do the rest. thanks!

    The pH of salts is determined by the hydrolysis of the salt. In the case of NH4Cl, the NH4^+ is hydrolyzed because it is a stronger acid than H2O (the NH4^+ donates a H^+ to H2O).
    .........NH4^+ + H2O ==> H3O^+ + NH3

    Ka for NH4^+ = (Kw/Kb for NH3) = (H3O^+)(NH3)/(NH4+)
    Substitute from the ICE chart and solve for x which is H3O^+, and convert that to pH.
