Marble And Hcl Experiment

An investigation of the reaction between marble chips and hydrochloric acid.

Marble and hcl experiment.

Marble chips calcium carbonate caco 3 react with hydrochloric acid hcl to produce carbon dioxide gas. 10cm3 of hydrochloric acid and 40cm3 of water 20cm3 of hydrochloric acid and 30cm3 of water 30cm3 of hydrochloric acid and 20cm3 of water 40cm3 of hydrochloric acid and 10cm3 of water and 50cm3 of just hydrochloric acid. A strong effervescence can be observed. The different concentrations of diluted water mixed with hydrochloric acid.

Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas. 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 rate of this reaction can be changed by changing the size of the marble chips. The volume of the hydrochloric acid will need to stay the same.

The mass of the marble chips in each test tube. Pieces of marble are thrown into hydro chloric acid. Plot the results on the same graph. Marble reaction with hydrochloric acid.

Click each image to see positive and negative results of the acid test. When calcium carbonate is added to hydrochloric acid a reaction takes place. Compare the slopes of the two graphs. Powdered marble reacts with hydrochloric acid to release bubbles of carbon dioxide gas.

Repeat the experiment with 20g of the same marble chip size and 20cm 3 of the acid made up to 40 using distilled water. Drop a small amount of dilute hydrochloric acid on an area of your sample that has been scratched by a nail. To ensure it is a fair test. In the investigation i am going to find out how the surface area affects the rate of reaction by measuring the amount of gas produced and weight loss in a reaction between small large pieces of marble chips calcium carbonate and hydrochloric acid per minute.

The reaction using a higher concentration of hydrochloric acid is faster. Using the apparatus shown the change in mass of carbon dioxide can be measure with time. I shall use quite a lot of apparatus for this experiment i shall need. Investigating the rate of reaction between marble chips calcium carbonate and hydrochloric acid aim.

Calcium carbonate is dissolved by hydrochloric acid thereby forming gaseous carbon dioxide. We are going to do an experiment to see how surface area effects the rate of reaction when added to hydrochloric acid. The time it takes for the marble chips to dissolve.
