Marble Chips And Hydrochloric Acid Experiment Graph

There are many variables that affect.

Marble chips and hydrochloric acid experiment graph. 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 a graph showing the loss of mass on the vertical y axis and time one the x axis. The essay on hydrochloric acid and marble reactions. Calcium chloride solution is also formed.

The graph which is most likely to. 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. Label this line a.

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. The reaction using a higher concentration. Marble chips calcium carbonate caco 3 react with hydrochloric acid hcl to produce carbon dioxide gas. An investigation of the reaction between marble chips and hydrochloric acid.

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. 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. 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. 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 rate of this reaction can be changed by changing the size of the marble chips. Repeat the experiment with 20g of the same marble chip size and 20cm 3 of the acid made up to 40 using distilled water.

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. Using the apparatus shown the change in mass of carbon dioxide can be measure with time. Draw a curve of best fit. Time s on the horizontal axis.
