Marble And Hydrochloric Acid

The reaction takes place spontaneously.

Marble and hydrochloric acid.

Task my task is to measure the rate of reaction between marble chips caco 3 and hydrochloric acid 2 hcl. Marble is crystalized caco3. To investigate the effect of concentration on the reaction between marble chips and hydrochloric acid materials. Marble reaction with hydrochloric acid.

Calcium carbonate is dissolved by hydrochloric acid thereby forming gaseous carbon dioxide. The combined reactants have a higher chemical potential than the combined products i e. Hydrochloric acid 20ml 0 5m 1m 2m marble chips 2g per test large measuring cylinder plastic bowl 3 4 full of water rubber tubing glass conical flask stopwatch method. The combined reactants have a higher chemical potential than the combined products i e.

The overall reaction is 2hcl caco3 cacl2 co2 h2o. When sulfurous sulfuric and nitric acids in polluted air and rain react with the calcite in marble and limestone the calcite dissolves. Drop a small amount of dilute hydrochloric acid on an area of your sample that has been scratched by a nail. Pieces of marble are thrown into hydro chloric acid.

A chemistry investigation to look at the rates of reaction between marble chips and hydrochloric acid. The reaction takes place spontaneously. Powdered marble reacts with hydrochloric acid to release bubbles of carbon dioxide gas. This experiment is to show how much carbon dioxide is produced during the reaction between an acid hydrochloric acid and marble.

Click each image to see positive and negative results of the acid test. Stone surface material may be lost all over or only in spots that are more reactive. Diagram plan the equipment i will be using for this experiment will be as follows.

Conical flask delivery tube bung measuring cylinder x 2 water trough water stopwatch marble. Calcium carbonate is dissolved by hydrochloric acid thereby forming gaseous carbon dioxide. A strong effervescence can be observed. Place 40cm 3 of hydrochloric acid in an conical flask.
