<u>Answer:</u> To calculate the pH of the buffer composed of , we use the
<u>Explanation:</u>
Phosphoric acid is a triprotic acid and it will undergo three dissociation reaction each having their respective dissociation constants.
The chemical equation for the first dissociation reaction follows:
The chemical equation for the second dissociation reaction follows:
The chemical equation for the third dissociation reaction follows:
To form a buffer composed of , we use the
of second dissociation process
To calculate the , we use the equation:
To calculate the pH of buffer, we use the equation given by Henderson Hasselbalch:
We are given:
= negative logarithm of second acid dissociation constant of phosphoric acid = 7.21
= concentration of conjugate base
= concentration of weak acid
Hence, to calculate the pH of the buffer composed of , we use the
