Hydrochloric acid (HCl) is a strong, corrosive acid that is commonly used in industrial and laboratory settings. It is also naturally produced in the stomach to aid in digestion.
Marble chips are small pieces of marble rock that are commonly used in chemistry experiments to demonstrate the effects of acid on a solid substance.
The symbol equation for this reaction is: HCl + CaCO3 → CaCl2 + CO2 + H2O
When hydrochloric acid and marble chips are mixed, a chemical reaction occurs. The acid breaks down the marble chips (calcium carbonate) into calcium chloride, carbon dioxide, and water.
The purpose of using marble chips in this reaction is to demonstrate the process of chemical weathering, where an acid (HCl) breaks down and dissolves a solid substance (marble) over time.
