Abstract
The process of mass dissolution has been investigated on the basis of the crystal-size distribution function in the case where the crystal faces traveled in accordance with the power law and the dissolution proceeded in a periodic regime. It has been proposed to reduce the dissolution problem to a system of equations that could be solved analytically in certain cases that are of interest in practice. The notion of dissolution efficiency has been introduced.
