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.
