# To Investigate a Factor Which Will Influence the Rate of the Reaction Between Calcium Carbonate and Hydrochloric Acid.

Extracts from this document...

Introduction

To investigate a factor which will influence the rate of the reaction between calcium carbonate and hydrochloric acid. In my investigation I hope to investigate how the concentration of a solution will influence the rate of reaction between calcium carbonate and hydrochloric acid. In order for particles (atoms, ions or molecules) to react together they must a) Collide with each other b) Have at least a certain amount of energy known as the activation energy. The rate of reaction is a measure of how fast the reaction takes place. I know that Acid + carbonate ? salt + water + carbon dioxide Hydrochloric acid + calcium carbonate ? calcium chloride + water + carbon dioxide 2HCl + CaCO3 ? ...read more.

In my investigation I intend to use the concentration as the independent variable. I will use different amounts of water in the range of 0 ? 40 cm3 to dilute the acid. I will take 5 readings at 10cm3 of water intervals so that I will be able to plot a graph. I can work out the new concentration using the formula New concentration = volume of acid / total volume x original concentration I will repeat each concentration and take an average. This will increase the accuracy of my results. I will put my results into a results table: - Volume of HCl (Cm3) Volume of H2O (cm3) Concentration of HCl (M) Volume of CO2 produced (cm3) Average volume of CO2 (cm3) ...read more.

Conclusion

Immediately start the stop clock. 6. Every 10 seconds take a reading off the gas syringe and record in results table. When 50 seconds has passed disconnect the leading tube and stop the stop clock. 7. Check mass of marble chips to make sure they are still 10g 8. Repeat steps 2-7 for accuracy. 9. Repeat the experiment for different concentrations. Apparatus 600cm3 beaker 100cm3 conical flask 10g marble chip (size three) HCl Bosshead Clamp Retort stand Gas syringe Bung Leading tube 100cm3 measuring cylinder Stop clock Balance Safety glasses Safety a) Wear safety glasses at all times. b) Always hold Gas syringe upright so that the cylinder does not fall out. c) Keep Gas syringe away from edge of desk. d) Don't throw marble chips down the sink. e) When measuring mass of the marble chips put paper on the balance so as not to scratch it.

This also could have affected it. I think that bearing in mind all these things that could have gone wrong, it is not surprising that I was faced with all these anomalies. Not all results fit in with the others. Occasionally they do not seem consistent as you can see in the graph.

Since the reactions involving the highest three molarities are so close in terms of their rates of reaction its not surprising there is slight deviation. However, the rates of reaction for each individual reaction are significantly lower than their corresponding middle point rates.

Key Factors Surface Area Particle size can also affect reaction rate. Marble chips will dissolve in hydrochloric acid more slowly than an equal amount of ground marble, because less surface area is exposed for the acid to attack.

The fact that it stopped at 54 shows that reaction was not very affective as at first the readings would go very fast then slow down towards the end. To balance this out we thought we should keep the same about of hydrochloric acid and M but change the calcium powder to 1.5g for the next experiment.
