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.

Marble and hydrochloric acid.

Calcium carbonate is dissolved by hydrochloric acid thereby forming gaseous carbon dioxide. Stone surface material may be lost all over or only in spots that are more reactive. A chemistry investigation to look at the rates of reaction between marble chips and hydrochloric acid. Calcium carbonate is dissolved by hydrochloric acid thereby forming gaseous carbon dioxide.

Pieces of marble are thrown into hydro chloric acid. Click each image to see positive and negative results of the acid test. To investigate the effect of concentration on the reaction between marble chips and hydrochloric acid materials. Conical flask delivery tube bung measuring cylinder x 2 water trough water stopwatch marble.

Diagram plan the equipment i will be using for this experiment will be as follows. The overall reaction is 2hcl caco3 cacl2 co2 h2o. Conical flask glass jam jars measuring cylinder stop clock watch with seconds stop watch app direct reading balance dilute hydrochloric acid cotton wool marble chips method. Hydrochloric acid to react with the marble chips independent variable marble chips to react with the acid dependent variable stopwatch to accurately time the experiment spatula to handle the marble chips measuring cylinder to precisely measure out different concentrations of hydryochloric acid electric balance to measure the mass g of the marble chips bung.

The combined reactants have a higher chemical potential than the combined products i e. The reaction takes place spontaneously. Marble is crystalized caco3. A strong effervescence can be observed.

The combined reactants have a higher chemical potential than the combined products i e. In exposed areas of buildings and statues we see roughened surfaces removal of material and loss of carved details. Place 40cm 3 of hydrochloric acid in an conical flask. Task my task is to measure the rate of reaction between marble chips caco 3 and hydrochloric acid 2 hcl.

This experiment is to show how much carbon dioxide is produced during the reaction between an acid hydrochloric acid and marble. Drop a small amount of dilute hydrochloric acid on an area of your sample that has been scratched by a nail. Marble reaction with hydrochloric acid. Pieces of marble are thrown into hydro chloric acid.
