Introduction

INVESTIGATION INTO HOW ACID RAIN AFFECTS THE SPEED OF CORROSION OF MARBLE STATUS Plan In my task is to see how limestone reacts with different concentrated (strengths) Nitric acid, each experiment I plan will need to be done twice. My set up equipment needs to be safe, "I don't want my results to go wrong". Fair testing I will need to do a faire test, so that all my results will look near enough the same (will be accurate). For a faire test everything must stay the same, a part from the concentrated strength acid and water. The mass of limestone will be the same, as well as the volume of acid and water. The room temperature will also stay the same. The measurements of acid and water will be different. The volume of acid and water will be 30cm3. If I changed the strength of acid I will see how different the limestone reacts with different strengths. The volume of water and acid will be divided into half's, quarters, and full strengths. ...read more.

Conclusion

To react strong enough they have to collide hard enough Scientific Knowledge Reaction rates are explained perfectly by collision theory. Its really simple it just says that the rate of a simply depends on how often and how hard the reacting particles collide with each other. The basic ideas is that particles have to collide in order to react, and they have to collide hard enough as well. Evaluating evidence By looking at my results the more strength acid is acting with limestone gives off more gas to be collected. By looking at my graph I'm noticing that the more strength acid, starts off fast. There reaction is taking places when collision are happening the more collision taking places = the more gas collected. The reason why full strength acid is the best is because more collision are happening with the limestone so more gas is coming off (being collected). If I had to improve my results I would recorded the temperatures more accurate than I did for my other experiment. I would also record the room temperatures as it might of effected my results. I would also do all experiment on the same day so that room temperatures is same for each experiment ...read more.

    It was difficult to get all the solute and washings into the volumetric flask without it over shooting the graduation mark, this occurred as the solutions were being made into too concentrated solutions. This over shooting took up much time as every time this occurred a new solution had to be made up.

    * turn the Bunsen burner off, 5�C before reaching my temperature target, so I do not over shoot it. The reason why I have to do this is because after turning off the Bunsen burner, heat energy is still transferred to the water bath, from the tripod, gauze, atmosphere and the beaker.

    This is not quite accurate because the reaction slows down over time. In the dilute acid it has time to slow down so it has a greater impact on the rate of reaction. At the start of the reaction there are little reacting acid particles, but they get used up

    This will lower the pollution from car exhausts and therefore less nitrogen oxide will be produced. People all around the world can make efforts to use electricity only when needed and not to waste it i.e. switching lights off and using energy saving appliances.

    CaCO3 + 2HCL CaCI2 + CO2 + H2O You can tell a reaction is taking place as gas is given off. Prediction With this knowledge, I predict that the higher the concentration of acid, the faster the reaction, (as there are more particles to collide with).
