A buffer is prepared by mixing 0.027 L of 0.029 M sodium bicarbonate and 0.021 L of 0.022 M NaOH. What is the pH?© BrainMass Inc. brainmass.com February 24, 2021, 2:30 pm ad1c9bdddf
There is a formula pH = pKa + log(A/HA)
were Ka is the acid dissociation constant, A and HA are the acid anion concentration and protonated acid concentration, respectively.
Also if you react sodium bicarbonate and NaOH...
NaHCO3 + NaOH --> Na2CO3 + ...
This solution is found using the formula pH = pKa + log(A/HA).
