Impact of Surface Area on Reaction Rates: A Chalk and HCl Experiment

This experiment aims to compare the reaction rates of powdered versus whole chalk when exposed to hydrochloric acid (HCl). The hypothesis posits that crushed chalk will react faster than whole chalk due to increased surface area, allowing for more efficient interaction with the acid. Using two beakers and HCl, we will observe and measure the time it takes for each chalk sample to react completely. Safety measures include handling HCl with care and wearing goggles to protect against its corrosive effects.
