| Abstract |
A Spodosol B horizon (base saturation of 5.4%) collected at the Watershed Manipulation Project site at Lead Mountain, ME, was used to examine soil solution chemistry in response to increasing solution levels of dissolved inorganic carbon (DIC). Acid-neutralizing capacity (ANC), determined by Gran titration, increased from -5 to 163 mw equiv/L in response to increasing DIC, with a corresponding increase in base cations (Ca2+, Mg2+, K+, and Na+). For the negative ANC solutions, degassing increased solution pH (in equilibrium with atmospheric CO2) slightly from 4.94 to 5.14, whereas solutions with positive ANC showed large pH shifts (e.g., ANC of 69, pH shift from 4.73 to 6.81). Under equilibrium assumptions and log K(sub A1) determined from 2.66pH-pAl, measured values from ANC, sum of cations, pH, and degassed pH were found to be in agreement with predictions from a chemical equilibrium model.
