An Experiment to Find Out How Much Gas is Given Off When Hydrochloric Acid and Marble Chips React

If hydrochloric acid and marble chips are used for the purpose of reaction, please investigate how much gas is released. This will tell you whether the concentration of hydrochloric acid will affect the reaction rate. Variable ========= I can change: temperature, rate of hydrochloric acid, number of marble chips, or marble chip size.

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

In this experiment, a large amount of marble and a large amount of hydrochloric acid were placed in an Erlenmeyer flask and fluff was used to collect absorbent cotton. When carbon dioxide is released from the flask, the mixture loses its mass and is measured and recorded every minute until the reaction is complete. I repeated the experiment again using the same quality marble chips and the same volume of hydrochloric acid at the same temperature, but using small marble fragments. When observing our results, we discovered that larger marble debris requires more time to react than smaller marble debris, which shows an increase in reaction rate as the surface area increases .

We accepted this experiment at a molar concentration of 0 M so 20 mL of water was added to 20 mL of water to reach 0 M. Then I will weigh 3 grams of marble chips of various sizes. Then I put marble chips in the beaker and then add hydrochloric acid. Then I will put hungry in the beakers as soon as possible. Then I let the reaction occur and record the amount of gas produced every 15 seconds for 90 seconds. Then I will repeat this experiment with medium and large chips. To confirm that there are enough measurements to reach the average value, repeat the experiment three times.
