The pH of buffered solution is:
The two buffered solutions have 'equal' pH values.
Comparison between two buffer solutions:
To compare the pH of two different buffer solutions with different concentrations, Henderson-Hasselbalch equation is used.
pH = pKa + log
pKa of HOAc = 4.76
In solution 1:
Concentration of salt= 5 M
Concentration of acid= 5 M
Putting the values in the equation,
pH = 4.76 + log
pH = 4.76 + log1
pH = 4.76
In solution 2:
Concentration of salt= 0.050 M
Concentration of acid= 0.050 M
Putting the values in the equation,
pH = 4.76 + log
pH = 4.76 + log1
pH = 4.76
As the ratio is the same for the different solutions.
Therefore, the pH of the solution remains the same in both the buffer solutions even if the two solutions have different concentrations.
