Marble And Hcl Experiment
The solution fizzes and gives off the gas carbon dioxide.
Marble and hcl experiment. The time it takes for the marble chips to dissolve. Plot the results on the same graph. When calcium carbonate is added to hydrochloric acid a reaction takes place. 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. Click each image to see positive and negative results of the acid test. We are going to do an experiment to see how surface area effects the rate of reaction when added to hydrochloric acid. Powdered marble reacts with hydrochloric acid to release bubbles of carbon dioxide gas.
The different concentrations of diluted water mixed with hydrochloric acid. 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. 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. Investigating the rate of reaction between marble chips calcium carbonate and hydrochloric acid aim.
Marble chips calcium carbonate caco 3 react with hydrochloric acid hcl to produce carbon dioxide gas. Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas. Pieces of marble are thrown into hydro chloric acid. The volume of the hydrochloric acid will need to stay the same.
The mass of the marble chips in each test tube. An investigation of the reaction between marble chips and hydrochloric acid. Calcium carbonate is dissolved by hydrochloric acid thereby forming gaseous carbon dioxide. Calcium chloride solution is also formed.
I shall use quite a lot of apparatus for this experiment i shall need. Compare the slopes of the two graphs. The reaction using a higher concentration of hydrochloric acid is faster. The rate of this reaction can be changed by changing the size of the marble chips.
I will add calcium carbonate marble chips to hydrochloric acid. Repeat the experiment with 20g of the same marble chip size and 20cm 3 of the acid made up to 40 using distilled water. Using the apparatus shown the change in mass of carbon dioxide can be measure with time.
