Abstract
The rates of dissolution of Ca(OH)2 in the form of rotating discs have been studied in water and in aqueous calcium nitrate and sodium hydroxide solutions, and have been found to be consistent with the rates of combined slaking and dissolution of CaO discs. A similar consistency has been found between rates of dissolution of powdered Ca(OH)2 and of powdered CaO in water. Our results support a mechanism for CaO slaking in which under moderate agitation the overall rate is controlled by diffusion of Ca2+ and OH− ions from the reacting surface, and under more vigorous agitation the dissolution of Ca(OH)2 at the surface controls the rate.
