Estimate the amount of Ca(OH)2(s) leached from concrete during a one-year period by precipitation. Assume that the area receives 40 in/yr of precipitation which is in equilibrium with PCO2= 10^-3.5 atm and [SO42-] = 10^-4 M. Assume that:
a. The rain and concrete reach equilibrium rapidly.
b. The remaining chemistry of the concrete does not impact leaching of Ca(OH)2(s).
c. Within the concrete, assume a closedsystem with CT in solution equal to that in the incoming precipitation
