Find out the effect of temperature on a reaction between Hydrochloric acid and Limestone.

Extracts from this document...

Introduction

Chemistry Investigation Aim: The aim of this investigation is to find out the effect of temperature on a reaction between Hydrochloric acid and Limestone. Variables which could affect my investigation: The variables, which could affect my investigation, are: - 1. Temperature because when liquids are heated they expand. 2. Volume of acid used because the more acid you use the easier it will be to react with other substances. 3. Mass of limestone used because there will be more of the substance to react with other substances. Variables which I am changing: The variable, which I am going to change, is as follows, temperature. Prediction: My prediction is that the higher the temperature is the quicker the reaction will displace water. ...read more.

Equipment I will use: The equipment I will use is as follows; - Conical flask, 2 Measuring tubes, Stopwatch, Clamp stand, Clamp, Water bowl, Water flask, Tube and bung, Hydrochloric acid, Limestone and Thermometer. Method: 1. The equipment will be set up as shown in the diagram. 2. Then I will put 20ml3 of Hydrochloric acid in the conical flask and make sure it is at the right temperature. 3. Then I shall put 6 grams of Limestone in the Conical flask putting the bung on top and making sure the tube is at the bottom of the measuring tube. 4. I will time the reaction at regular intervals (every 30 seconds) for 90 seconds. ...read more.

Conclusion

Thus making the reaction quicker. My prediction was right as the particles did vibrate more when heated and more collisions happened as a result of this thus making the reaction quicker. Also when the substance gets heated too much the bonds break as stated in my prediction and shown to be correct in my result table. Evaluation: The experiment I have just done could have been extended by allowing us as a group to have a longer time to do this investigation. This would also increase our knowledge and help us to explain it more and record more results thus making the experiment more reliable. Also we would have been able to repeat the experiments more times thus making the practical more reliable in terms of scientific knowledge. - 2 -Fernand Hyam 11E ...read more.

    Then you can see how each of the variables affected the reaction. Method 2: Set up the apparatus as shown in diagram (below). Warm the acid up first before adding it to the experiment as shown in the diagram (below).

    the limestone, the temperature of the acid, the surface area and volume of the acid. To see if the temperature does affect the rate that limestone dissolves in acid, I will see how long it takes to produce 40cm� of carbon dioxide.

  2. How much water is displaced during the reaction between limestone and hydrochloric acid?

    The factors, which may affect how well the experiment works, are how quickly the chips are put in and then the bung placed on and the stopwatch pressed. Although this is a factor it is not really a major factor that will affect the end results, and as long as

  1. How Much Does Limestone React With Hydrochloric Acid?

    The strategy I choose to take is that of placing the limestone into the acid, activating the stopwatch, and putting the bung in the top of the flask as quickly as possible. There will be 50 millilitres of water in the glass tube.

  2. To find out what effects the weathering of the limestone building.

    The powder will react faster then the rest because it has lots of small particles so the acid shell react faster, and when you put the acid and the powder in the conical flask make sure to out the lid on straight away or lots of gas will escape.
