The Rate of Reaction Between Hydrochloric Acid and Marble Chips

Reaction rate of hydrochloric acid and marble fragmentation plan In this experiment we will investigate the reaction rate of hydrochloric acid (HCl) and marble chips. For this purpose, I change the concentration of HCl, measure its effect on the amount of CO 2 produced during the reaction, and find the rate. We predict that increasing the concentration will increase the reaction rate. I think that this is due to particle theory.

I anticipate that adding a small piece of marble to hydrochloric acid makes the reaction faster and therefore more gas (carbon dioxide) released. This is due to the large surface area of ​​small marble fragments. Addition of large marble chips to hydrochloric acid slows the reaction rate, resulting in less gas evolution. This is because marble chips have small surface area. This means that using smaller marble chips can produce 100 cubic centimeters of carbon dioxide faster.

In this survey we use CaCO 3 in the form of marble chips and react these chips with hydrochloric acid. The equation for this is as follows. PURPOSE: We are investigating whether the temperature affects the reaction rate of the experiment. The experiment I am doing is how temperature influences the release rate of gas when hydrochloric acid is added to calcium carbonate in the form of a marble chip. 2HCL (aq) + CaCO 3 (s)? H 2 O (I) + CO 2 (g) + CaCl 2 (aq) Preliminary experiment program, evaluation and prediction

Examine how acid concentration affects the reaction rate of hydrochloric acid and calcium carbonate (magnesium band) --- My goal is how acid concentration changes influence the reaction rate of CaCO 3 and HCl It is to investigate. We change only one of the variables to make the experiment fair. It is the concentration of acid. In all the experiments we had to maintain the amount of acid, the quality and size of the marble chip, and the temperature of the acid to ensure a fair test.
