Calculate the pH of 100.0 mL of a buffer that is 0.0850 M NH4Cl
and 0.180 M NH3 before and after the addition of 1.00 mL of 5.50 M
HNO3.
Can you please do a step-by-step of how to solve this,
paying special attention to how to get the Ka in the Henderson
Hasselbalch Equation? That's the part I'm not
understanding.
Calculate the pH of 100.0 mL of a buffer that is 0.050 M NH4Cl

A 100.0 ml buffer solution is 0.20 M HC7H5O2 and 0.15 M
NaC7H5O2. Calculate the pH of the solution after the addition of
0.0025 moles of NaOH. Assume the volume of the buffer does not
change. (HC7H5O2 = Ka 6.5x10^-5)
Calculate the pH of the 0.250 M NH3/0.5 M NH4Cl buffer system. What
is the pH after the addition of 2.0 mL of 0.250 M NaOH to 18.0 mL
of the buffer solution? After adding 10 more mL of 0.25 M NaOH what
is the pH?
A buffer is 0.10 M in NH3 and 0.10 M in NH4Cl. What is the pH of
the solution after the addition of 10.0 mL of 0.20 M of HCl to
100.0 mL of the buffer?
