Calcium Carbonate And Hydrochloric Acid Coursework-78
Rate of reaction between Hydrochloric Acid and Calcium Carbonate Calcium carbonate reacts with hydrochloric acid to form carbon dioxide gas.One way of following the rate of reaction at which it reacts is to measure the volume of carbon dioxide produced at certain time intervals during the reaction.The collision theory will be involved in this, for instance the more concentrated the acid we use, the faster the reaction will occur and the Experiment to investigate factors affecting the rate of reaction between magnesium ribbon and hydrochloric acid Rates of Reaction: Investigation Experiment to investigate factors affecting the rate of reaction between magnesium ribbon and hydrochloric acid.

Rate of reaction between Hydrochloric Acid and Calcium Carbonate Calcium carbonate reacts with hydrochloric acid to form carbon dioxide gas.One way of following the rate of reaction at which it reacts is to measure the volume of carbon dioxide produced at certain time intervals during the reaction.The collision theory will be involved in this, for instance the more concentrated the acid we use, the faster the reaction will occur and the Experiment to investigate factors affecting the rate of reaction between magnesium ribbon and hydrochloric acid Rates of Reaction: Investigation Experiment to investigate factors affecting the rate of reaction between magnesium ribbon and hydrochloric acid.

Introduction In the experiment the magnesium reacts with the hydrochloric acid to create magnesium chloride and hydrogen.

The balanced formula for this is: Mg(s) 2HCL(aq) Mg Cl2(aq middle of the investigation then the rate of reaction will be affected.

If I had a wide range of molarities, it would be easy to see this pattern.

METHOD Before conducting our experiment where we would get our facts and evidence from, we carried out a pre-test.

This is because for the Rates of Reaction - Sodium Thiosulphate and Hydrochloric acid In this piece of coursework, I will study how concentration affects the rate of reaction.

I will do so by timing the reaction of Sodium Thiosulphate with an acid.Variables: The concentration of Sodium Thiosulphate will be changed throughout the investigation and this makes it the independent variable in my investigation.In my investigation the dependent variable will be the time it takes for the reaction between Sodium Thiosulphate and Hydrochloric acid to take place.Therefore, because they are closer the particles will collide more often.The more often they collide the more chance they have of producing a productive reaction.If the molarity of the acid concentration is doubled, the rate of reaction will double.This is because the particles are closer together in a concentrated solution.RATE OF REACTION BETWEEN HYDROCHLORIC ACID AND CALCIUM CARBONATE LOW CONCENTRATION HIGH CONCENTRATION I think that during our experiment, the higher the molarity of acid the quicker the rate of reaction will be, I think this because of the collision theory.If the solution is made more concentrated, there will be more particles in the solution.(Because there will be more collisions between sodium thiosulphate and hydrochloric acid.)Describe how you will ensure your results are as accurate, reliable and precise as possible increase the concentration of the Hydrochloric acid, the frequency of collisions increased so the rate of reaction also increased.This is because the higher the concentration of Hydrochloric acid the more frequent the collisions will be between the Magnesium strip and Hydrochloric acid particles.

    Acid particles bump into the calcium carbonate very frequently and if they do this, the surface of the limestone will dissolve quickly. If the acid is very dilute then the particles will be more spread out. They will bump into the limestone a lot less often and so the reaction will take longer.…
