a. Calculate the pH for the Beijing
precipitation. Remember sulfate and nitrate are the major
contributors to acidity.
b. Does the calculated pH agree with the
measured pH?
c. Using the measured pH, calculate the
bicarbonate ion concentration. Assume that the temperature is
25°C.
d. Write a charge balance equation using all
the positive and negative species. Is there a charge balance?
e. Taking into account the results from part
(d), explain any difference that exists between the observed pH and
the calculated pH.
