||The purpose of this study is to investigate the rate and kinetic formulation of chemical weathering on an isolated fraction of whole soil, specifically, whether the rate of chemical weathering is proportional to a fractional power of the hydrogen ion activity in soil solution, a kinetic formulation that is consistent with a surface-reaction-controlled dissolution mechanism. Weathering experiments were also conducted to investigate the effect of an accumulation of base cations (near saturation for kaolinite) on the weathering rate in the semicontinuous mode of operation of a laboratory pH-stat reactor.
