Given information
The ionization constant is the product of molar concentrations of hydronium ion and hydroxyl ion concentrations.
From hydronium ion concentration, pH can be calculated as
Step-by-step explanation
Step 1.
The change in concentrations is calculated from the below table:
The equilibrium constant for the above reaction is,
The concentration of and is equal in magnitude and it is assumed to be .
from the above equation,
The concentration of is .
