Calculate the pH of a buffer that is 0.13 M in lactic acid and 0.11 M in sodium lactate

Sagot :

acidity of lactic acid = pKa = 3.85
Ca = 0.13M
Cs = 0.11M
Henderson-Hasselbalch equation:
pH = pKa + log(Cs/Ca)
pH = 3.85 + log(0.11M/0.13M) = 3.85 + log0,846 = 3.85 - 0.073 = 3.777

The pH value of the buffer  is mathematically given as

pH=  3.77

What is the pH value of the buffer?

Question Parameters:

The pH of a buffer that is 0.13 M in lactic acid and 0.11 M in sodium lactate

Generally, the equation for the pH  Value  is mathematically given as

pH = pKa + log(Cs/Ca)

Where

Ca = 0.13M

Cs = 0.11M

Therefore

pH = 3.85 + log(0.11M/0.13M)

pH= 3.85 + log0,846

pH= 3.85 - 0.073

pH=  3.77
