Abstract: 
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. The phenomena of external and internal diffusion during the dissolution of boric acid spheres in water under agitation were also examined. To evaluate the mass transfer process, a generalized criterion equation was used that takes into account all the factors under study. Comparison of experimental and theoretically calculated values showed that the maximum absolute relative error does not exceed 6%. The results obtained are valuable for further research and potential applications in the chemical industry, pharmacology, and cosmetology.
