Dgfhhdhdinvestigating rates of reaction aim the aim of my investigation is to find out how rates of reaction are affected by temperature specifically how the rate of the reaction between hydrochloric acid and marble chips is affected by the temperature of the hydrochloric acid.
Marble chips and hydrochloric acid experiment graph.
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.
Marble chips calcium carbonate caco 3 react with hydrochloric acid hcl to produce carbon dioxide gas.
Plot the results on the same graph.
Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas.
Volume of gas cm 3 on the vertical axis.
Plot a graph showing the loss of mass on the vertical y axis and time one the x axis.
Compare the slopes of the two graphs.
There are many variables that affect.
For each concentration of hydrochloric acid plot a graph to show.
Investigating the rate of reaction between marble chips calcium carbonate and hydrochloric acid aim.
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.
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.
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.
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.
Label this line a.
The essay on hydrochloric acid and marble reactions.
The rate of this reaction can be changed by changing the size of the marble chips.
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.
The graph which is most likely to.
Draw a curve of best fit.
Calcium chloride solution is also formed.
Time s on the horizontal axis.
