GCSE Chemistry - Limestone and Carbon Dioxide Coursework

Extracts from this document...

Introduction

GCSE Chemistry - Limestone and Carbon Dioxide Coursework Hypothesis I think that the smaller limestone chips will produce the greater amount of carbon dioxide than the larger chips as there will be a greater surface area for the acid to react upon. This is because the greater the surface area the higher the amount of collisions between limestone and acid particles. Therefore the smaller chips will lose a greater mass. The formula for this reaction is Marble + Hydrochloric = Carbon + Water + Calcium Chips Acid Dioxide Chloride CaCO3(s) + 2HCL(aq) = CO2(G) + H2O(l) ...read more.

� Wear goggles at all times. � Be careful dropping limestone into glass beakers. Fair Test Variable Particle Size Factors remaining the same Same mass of limestone Same volume of acid Same molar acid Apparatus Large Beaker Weighing Scale Measuring Cylinder Spatula Stopwatch Cotton Wool Obtaining Analysing Conclusion. The prediction I made was correct as the smaller the particle size the greater the mass loss. This is because of the collision theory - the higher the total surface area the more particles can collide and react. ...read more.

Conclusion

Also there could be some human error, making inaccurate timing and starting mass making an unfair test. Evaluating Evaluation My experiment went well but we did not have time to do the small granules so we used a class set of results only for the small granules. There doesn't seem to be any odd results on the graph. The reason we did not have enough time because there were not many digital balances. We could have been more organised by sharing jobs. If the class had enough balances then we would of finished in time. The reason we had no odd results because the balance was digital and to two decimal places. ...read more.

  1. Investigating Membrane Permeability.

    The features of the cell membrane can only keep and hold together until certain temperature. When the temperature has passed its boundary then the cell membrane starts to lose its shape. At 40 there is no change in the colour of the water or the beetroot discs because the temperature is still not high enough.

  2. An Investigation of the weathering of limestone.

    Measurements and Trials: In our experiments we will change the concentration of the acid five times. This way we will be able to get a clear picture of how the concentration of the acid affects the rate of reaction on the limestone.
