Question
Can you help me figure out how to solve the following?Calculate the pH of a solution that is .30 M in ammonia (NH3) and .20 m in ammonium chloride ( NH4Cl , Ka=5.62x10^-10)?
What is the pH of a .25m NH4Cl solution with Ka=5.68x10^-10? Can you help me figure out how to solve the following?

Explanation / Answer
pH=pKa + log [base]/[acid]
=-log(5.62*10^-10) + log [0.30/0.20]
=9.25 + 0.1760=9.426
for [NH4+]=0.25M
pH=pKa + log [base]/[acid]
=-log (5.68*10^-10) + log [0.30/0.25]
=9.246+0.07936
=9.325
