I've been asked to find the pH of NH4OH 0.1 M and NH3Cl 0.05 M.
I tried these reactions:
NH4OH <==> NH4 + OH with Kb=1.8 E 5- (1)
NH3Cl ---> NH3 + Cl
NH3 + H20 <===> NH4 + OH (2)
then then the concentration of NH4 and the concentration of OH is the sum of NH4 and the sum of OH I carry from (1) and the NH4 and OH due to the reaction (2), and the pH will be
pH=14-pOH of reaction (2).
I'll appreciate you to tell me if that's ok.
Thanks a lot.
