Extracts from this document...

Introduction

Title: Hydrochloric Acid and Marble Chips Aim: Find the rate of reaction when dissolving marble chips in Hydrochloric acid. Hypothesis: The rate of a chemical reaction is a measure of how quickly a reaction takes place. One or more of the following can easily affect this: * The particle size * The concentration * The pressure * The temperature * The presence of a catalyst I will talk about each of these affects in turn. 1) The particle size used within solids and liquids are normally dealt with in smaller particles of the solid reactant. This is because the atoms or ions on the surface of the particle are the cause of the reaction by mass. ...read more.

Middle

Changed variables: the volume of acid used and the time taken to collect 50ml of gas. Constant variables: the concentration of the acid and the amount of marble chips used Prediction: when reacting marble chips with hydrochloric acid, I predict that the greater the volume of acid that is used at a constant concentration, the greater the amount of gas will be given off in a shorter amount of time. Apparatus: Conical flask Delivery tube Measuring cylinder Water basin Stop watch/ stop clock Rubber bung Hydrochloric acid Marble chips Water Diagram: Method: 1) Set up the apparatus as shown above 2) Produce adequate results table as shown over-leaf 3) ...read more.

Conclusion

12) Repeat steps 4 to 11 until you have collected an efficient amount of results then record your finding on a graph. Results table: Acid concentration (M) Mass of marble chips (G) Volume of acid (Cm�) Volume of gas (Ml) Time taken (Sec) 1.0 1.0 10 50 68 1.0 1.0 5 50 134 1.0 1.0 10 50 68 1.0 1.0 10 50 23 1.0 1.0 15 50 61 1.0 1.0 20 50 58 1.0 1.0 25 50 56 1.0 1.0 30 50 55 1.0 1.0 35 50 52 1.0 1.0 30 50 50 1.0 1.0 35 50 49 Conclusion: my results show a pattern similar to that of my prediction. If I was to repeat this experiment then I would use the volume of acid in multiples of 5 and I would do the experiment twice as to produce a fair test. ...read more.

    There are several reasons why this could have happened. These are: That the acid could have been stronger; or the surface area of the marble chips could have been bigger. The first of these is hard to justify, but could have happened if by accident more acid than was supposed to be put in was put in.

    will collide so increasing the reaction rate. When hydrochloric acid (HCl) is added to calcium carbonate (CaCO3) the two substances react giving this equation: CaCO3 + 2HCl � CaCl2 + H2O + CO2. This shows that when the two react, calcium chloride, water and carbon dioxide are all given off and the gas that fills the measuring cylinder is CO2.
