This study investigates the effects of shell powder particle size and stirring methods on the dissolution of calcium carbonate (CaCO3) into calcium bicarbonate (Ca(HCO3)2), focusing on mechanochemical principles. Smaller particle sizes increased dissolution efficiency by providing more reactive sites. Among stirring methods, impact stirring was most effective, followed by rolling and hand shaking. In contrast, the control group with saturated carbonated water alone showed no significant dissolution. These findings underscore the importance of optimizing particle size and stirring methods for efficient mechanochemical processes. |
