Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas.
Marble chips and hydrochloric acid experiment graph.
The reaction using a higher concentration.
The essay on hydrochloric acid and marble reactions.
The graph which is most likely to.
Label this line a.
Investigating the rate of reaction between marble chips calcium carbonate and hydrochloric acid aim.
Volume of gas cm 3 on the vertical axis.
For each concentration of hydrochloric acid plot a graph to show.
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.
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.
Compare the slopes of the two graphs.
There are many variables that affect.
Calcium chloride solution is also formed.
An investigation of the reaction between marble chips and 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.
Draw a curve of best fit.
Plot a graph showing the loss of mass on the vertical y axis and time one the x axis.
The rate of this reaction can be changed by changing the size of the marble chips.
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.
Plot the results on the same graph.
Using the apparatus shown the change in mass of carbon dioxide can be measure with time.
Time s on the horizontal axis.
The graph which is most likely to be produced from experiment 3 is graph a the only difference in the conditions compared with experiment 1 is that there is twice as much acid.
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.
Marble chips calcium carbonate caco 3 react with hydrochloric acid hcl to produce carbon dioxide gas.
