When you add powdered limestone to lemon juice whatwould you see happening?

When powdered limestone (calcium carbonate) is added to lemon juice, a chemical reaction occurs due to the acidity of the lemon juice, which contains citric acid. This reaction produces carbon dioxide gas, resulting in visible bubbling or fizzing as the gas escapes. Additionally, the limestone may start to dissolve, leading to a cloudy solution as the calcium ions interact with the acidic components. Overall, the mixture will exhibit effervescence and a change in appearance.
