Question

a) What is the pH of water in equilibrium with 0.040 ppm SO2 gas? The total air
pressure is 1.02 atm. Assume that no further oxidation occurs in the air or water.
KH = 1.0; Ka1 = 1.7 x 10-2; Ka2 = 1.2 x 10-7
b) Would the resulting pH be higher or lower than the pH from (3a) if further
oxidation did occur in the air? Explain.
