Dissolution Rate of Flat Plate Limestone in Agitated Sulfuric Acid Solution

Abstract:

In this study, a flat plate limestone of which surface area was accurately defined was dissolved into acid in an agitated vessel. Dissolution rates of limestone were measured under various agitation speeds, temperatures and acid concentrations. As a result, it was found that the rates were controlled by the diffusion of particular chemical species depending on acid concentration.
