When acid is added to crushed marble, a chemical reaction occurs between the acid and calcium carbonate in the marble, producing carbon dioxide gas, water, and a salt. Stirring the mixture enhances the reaction by increasing the contact between the acid and the marble particles, allowing for more effective dissolution and gas release. This agitation accelerates the reaction rate, leading to a quicker production of bubbles and more vigorous effervescence. Overall, stirring facilitates a more uniform and rapid reaction within the system.
