Abstract
AbstractGross dissolution of natural rhombohedral calcite crystal in concentrated nitric acid in dynamic etching condition is studied and interesting results are obtained. The gross dissolution is maximum at 6 molar concentration of nitric acid in dynamic etching condition which is similar to static etching condition. The activation energy and pre‐exponential factor is calculated for different concentrations (range 3.0 to 7.5 molar) of nitric acid. The values of activation energy and pre‐exponential factors increase as concentration increases in dynamic etching, and it is more than static etching. The higher values of gross dissolution, activation energy, and pre‐exponential factor in dynamic etching condition is explained.
