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