please explain with more words if you are possible

-
You get a solution of sulphur dioxide dissolved in water.
A very small amount will combine with the water to give sulphurous acid:
SO2(g) + H2O(l) → H2SO3(aq)
this is a weak acid.

-
THE FOLLOWING REACTION WILL TAKE PLACE------
SO2 + H2O ------------------> H2 SO3 (sulfurous acid ]
H2 SO3 is unstable weak acid

-
SO2 has a solubility of 94g/dm^3 and its pKa = 1.9
