Calcium chloride solution is also formed.
Marble chips and hydrochloric acid experiment graph.
Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas.
Label this line a.
Investigating the rate of reaction between marble chips calcium carbonate and hydrochloric acid aim.
Plot a graph showing the loss of mass on the vertical y axis and time one the x axis.
There are many variables that affect.
Volume of gas cm 3 on the vertical axis.
Compare the slopes of the two graphs.
This will not make any difference to the graph as it is the marble chips that are used up not the acid so the graph will be the same.
An investigation of the reaction between marble chips and hydrochloric acid.
Hydrochloric acid marble chips the experiment the aim of this experiment is to find out how different variables affect the rate at which the reaction between marble chips caco and hydrochloric acid hcl takes place.
Plot the results on the same graph.
9 3 sketch a line on the grid in figure 10 to show the results you would expect if the experiment was repeated using 20 g of smaller marble chips.
The reaction using a higher concentration.
Marble chips calcium carbonate caco 3 react with hydrochloric acid hcl to produce carbon dioxide gas.
The rate of this reaction can be changed by changing the size of the marble chips.
The essay on hydrochloric acid and marble reactions.
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.
Using the apparatus shown the change in mass of carbon dioxide can be measure with time.
Time s on the horizontal axis.
2 marks 9 4 explain in terms of particles how and why the rate of reaction changes during the reaction of calcium carbonate with hydrochloric acid.
The graph which is most likely to.
Repeat the experiment with 20g of the same marble chip size and 20cm 3 of the acid made up to 40 using distilled water.
Draw a curve of best fit.
