Problem- Calculate the change in pH when 4.00mL of 0.100 M HCl(aq) is added to 100.0mL of a buffer solution that is 0.100 M in NH3(aq) and 0.100 M in NH4Cl(aq).
Calculate the change in pH when 4.00 mL of 0.100 M NaOH(aq) is added to the original buffer solution.
I need expert help to solve the above question. Show each and every step.
