Let us write the appropriate equilibria and associate the correction values. Remember, we will want to calculate the concentrations of all species in a 0.390 M Na ₂SO₃ (sodium sulfite) solution. The ionization constants for sulfurous acid are = 1.4 × 10⁻² and = 6.3 × 10⁻⁸.

Explanation:

The relation between is given by :

Where :

= Ionic prodcut of water

The value of the first ionization constant of sodium sulfite =

The value of :

The value of the second ionization constant of sodium sulfite =

The value of :
