<span>Given:
acid-dissociation constants of sulfurous acid</span>:
Ka1 = 1.7 * 10^(-2)
Ka2 = 6.4 * 10^(-8) at
25.0 °C.
aqueous solution of
sulfurous acid = 0.163 M
x² / (0.163 - x) = 1.7 * 10^(-2)
You simplify it to:
<span>x² / (0.163) = 1.7 *10^(-2) </span>
x = 0.052640 M
pH = 1.28
<span>
So, the pH of a 0.163 M aqueous solution of sulfurous acid is 1.28.</span>
To add, aqueous solutions of sulfur dioxide purpose
are as disinfectants and reductant, as are solutions of sulfite<span> salts
and </span>bisulfite. By accepting another oxygen<span> atom, they
are </span>oxidised to sulfuric
acid or sulfate.
