A. Seidel et al., THE KINETICS OF DISSOLUTION OF SILICA MONOSPHER INTO WATER AT DIFFERENT CONCENTRATIONS OF BACKGROUND ELECTROLYTE, Solid state ionics, 101, 1997, pp. 713-719
The kinetics of dissolution of silica 'Monospher' into water as regard
s its dependence on time and pH was investigated at background electro
lyte concentrations of 0, 0.001, 0.01 and 0.1 mol l(-1). The dissolved
amount of silica depicted as a function of time and pH forms a dissol
ution surface. This surface can be modeled by four deprotonation equil
ibria and four elementary reactions. The concentration of background e
lectrolyte increases the rate of dissolution and influences the shape
of the dissolution surface.
