Mass Transfer during Boric Acid Dissolution

The process of mass transfer during the dissolution of boric acid spheres in water was investigated in the temperature range from 293 K to 323 K, and at stirring rotation rates from 1.67 to 6.67 s-1. The study aimed to determine the dependence of the dissolution rate on the stirring rotation rate and water temperature. The analysis of the experimentally obtained results revealed that the most significant factor affecting the intensification of the dissolution process is an increase in the solution temperature.
