If they have more energy there is greater chances of successful collisions meaning the reaction occurs faster. Free Essays words 2. Hydrochloric acid is also produced in the stomach, where it initialises the digestion of proteins. Sodium thiosulphate is a white crystalline salt used as a fixer in photography and as a sodium thiosulphate and hydrochloric acid coursework. Free Essays words 4.

Prediction: I predict that as the concentration of the Sodium Thiosulphate doubles, the rate of the reaction will double. I believe that when the most concentrated solution is used the reaction would be at its fastest. Collision Theory: In a more concentrated solution there are more particles so collisions occur more frequently Free Essays words 1.

I will also investigate if there sodium thiosulphate and hydrochloric acid coursework be a change in temperature after the reaction has occurred. I will know when the reaction is taking place as the solution turns from clear to opaque. Free Essays words 3. When mixed together, these form a yellow precipitate.

Free Essays words 4 pages. It is a precipitation experiment. Free Essays words 7, sodium thiosulphate and hydrochloric acid coursework. PLAN A chemical reaction takes place over a specific period of time i. If the reactants take a relatively short time to form the products, the reaction is known as a FAST one. The RATE of that particular reaction is high. On the other hand, a reaction which takes a longer time is known as a SLOW reaction, and as a result is known to have a LOW rate of reaction Research Papers words 6.

Introduction: This experiment will be carried out by drawing a cross on a piece of paper and mixing hydrochloric acid and sodium thiosulphate together to see if the cross disappears. The concentration of hydrochloric acid would change every reaction to show that concentration effects a reaction Research Papers words 3.

This causes the reaction to happen more rapidly therefore making a cloudy substance much quicker Free Essays words 3 pages. Planning; Aim To see how the concentration of acid affects the rate of reaction in the reaction between hydrochloric acid and sodium thiosulphate.

Background; All reactions occur because of the particles that make up the reactants will collide, and if they have sufficient energy, react forming or breaking bonds, sodium thiosulphate and hydrochloric acid coursework. All four methods of increasing the rate of reaction can be explained in terms of increasing the number of collisions Free Essays words 6.

The Hydrochloric Acid, Sodium Thiosulphate Reaction Essays - The Hydrochloric Acid, Sodium Thiosulphate Reaction Research: "Hydrochloric acid is a strong colourless acid formed when hydrogen chloride gas dissociates in water, used in industrial and laboratory processes.

Reaction Between Hydrochloric Acid and Sodium Thiosulphate Essay - Reaction Between Hydrochloric Acid and Sodium Thiosulphate Introduction I will be conducting two experiments to determine how two factors affect the rate of reaction in the reaction between hydrochloric acid and sodium thiosulphate. How concentration affects the rate of reaction between Hydrochloric Acid and Sodium Thiosulphate - How concentration affects the rate of reaction between Hydrochloric Acid and Sodium Thiosulphate Chemistry Coursework How Concentration Affects a Reaction Aim: The aim of this experiment is to find out how concentration affects the rate of reaction between Hydrochloric Acid and Sodium Thiosulphate.

Investigating the Effect of Concentration on the Speed of the Reaction Between Hydrochloric Acid and Sodium Thiosulphate - Investigating the Effect of Concentration on the Speed of the Reaction Between Hydrochloric Acid and Sodium Thiosulphate Prediction: My prediction is, the higher the concentrations, the faster the reaction will occur in my experiment to make the x on the sheet on paper disappear. The Rate of Reaction in the Reaction Between Hydrochloric Acid and Sodium Thiosulphate - To see how the concentration of acid affects the rate of reaction in the reaction between hydrochloric sodium thiosulphate and hydrochloric acid coursework and sodium thiosulphate.

Popular Essays Creationism in Public Schools The Effect of Temperature on the Rate of Reaction An investigation into whether the voltage affects the amount of gas produced during the electrolysis of sodium chloride solution Rate of Reaction Rate of Reaction How the concentration of an acid affects the rate of reaction on marble chips.

Search Term:. Record the results 8. Clean out apparatus briefly with water 9. Repeat 3 times for each amount of and do it from ml. My results Here is a table of my results, sodium thiosulphate and hydrochloric acid coursework. I have performed the experiment three times for each strength of solution, to get the best possible results, as well as a good average. My results were not very accurate, but I only had two results, which seemed abnormal.

I have highlighted these in red. I rounded off all results; if it was Also the human has a reaction time of 0. I have also drawn a graph, showing my results, this has been drawn using the averages. Analysis The pattern I have found is that the stronger the Sodium Thiosulphate the quicker it reacts. I have looked for stronger patterns, but I can tell from my results that the graph will be a curve, sodium thiosulphate and hydrochloric acid coursework, and that it fits sodium thiosulphate and hydrochloric acid coursework 'Collision Theory'; twice the amount of particles in the same volume means twice the chance of collision; in theory half the time of reaction.

My results do fit my prediction. The general rule for this is 'the stronger the solute, the faster the reaction. There was a lot that I could have carried out to make sodium thiosulphate and hydrochloric acid coursework results even more accurate. On some tests, we gently 'swished' the liquid around in the flask, and others we did more vigorously, or not at all. To make it more accurate, be consistent in what I chose to do. To tell at which exact point the solute becomes opaque is another issue, and how dense it becomes.

We got round this by the same person measuring it every time, but a more accurate way would be to use a light sensor, or another devise, to make it more accurate. The temperature of the liquids might have made some reactions faster or slower, so a room with a controlled temperature would help, sodium thiosulphate and hydrochloric acid coursework.

The conclusive theory is that 'twice the amount of particles in the same total volume means twice the chance of collision therefore in theory half the time of reaction'-Collision Theory. This is due to a high concentration, explained above. The higher percentage chance of hitting the acid is also explained using a diagram on a previous page. Basically the more particles of Sodium Thiosulphate stronger solution the quicker it reacts because the chance of collision is increased, giving it the optimum reaction time.

This gives a curved graph, shown on sodium thiosulphate and hydrochloric acid coursework graph paper. Return to HelpMe.
