Next I will place the conical flask on top of the cross, pour 5cm3 of hydrochloric into the hot sodium thiosulphate solution and time how long it takes for the cross to disappear.
The quality of my evidence is good. I will also try to make my timing and the heating of the sodium thiosulphate solution as accurate as possible.
Therefore, I will make sure that I only change the temperature of the reaction mixture and keep the volume and concentration of the sodium thiosulphate, the volume and concentration of hydrochloric acid and the pressure of all the mixtures the same.
I could also change the initial volume of either the hydrochloric acid or sodium thiosulphate solution and see if I get a similar pattern of results. From this evidence I believe my results were very reliable.
Furthermore I will be careful not to spill anything and will take extra care when doing the experiment. In addition I am also checking how different variables affect my experiment and also how I can make my test more precise, reliable and accurate.
Rate of Reaction — Sodium Thiosulphate and Hydrochloric Acid Coursework Aim Investigation, to find out how the rate of reaction between Sodium Thiosulphate and Hydrochloric acid is affected by changing the concentration.
Sodium thiosulphate decomposition for GCSE, grade a easy. An investigation to show how the rate of reaction between hydrochloric acid and sodium thiosulphate is affected by the concentration of the acid Simple Procedure Place a conical flask on a piece of paper with a cross on it.
I will then put 40cm3 of sodium thiosulphate into a conical flask and place it on a tripod and gauze. In order to provide additional evidence and extend my investigation to find out more and back up my conclusion I could perhaps repeat the experiment using specialist equipment.
Sodium Thiosulphate And Hydrochloric Acid Coursework A kinetic study of the reaction between aqueous sodium — Rates of Reaction — Sodium Thiosulphate and Sodium Thiosulphate CourseworkThe Coursework on Help with rates of reaction coursework Hydrochloric acid and I am doing coursework on the rate of reaction between Hydrochloric acid and Sodium Thiosulphate To avoid confusing I will describe the test I tried and then will tell the problems I had.
I am going to draw a graph analyse by results properly. Safety I will make sure I handle the sodium thiosulphate solution and hydrochloric acid with care. My results do support the first part of my prediction.
I will also be careful when heating up the solutions and will at all times wear safety goggles and also remain standing throughout the experiment.
From Wikibooks, For the hydrochloric acid — sodium thiosulphate reaction you can plot either i reaction time, or Disappearing X Experiment.
Furthermore I will measure out the volumes of both the sodium thiosulphate and hydrochloric acid to the greatest degree of accuracy I can manage. Variables There are different variables which can be changed. Results Below is a table showing my results from the main investigation I can see from observing the table that the first part of my prediction was correct.
The independent variables will be the initial volume and concentration of sodium thiosulphate, and the initial volume and concentration of hydrochloric acid. Below are diagrams to illustrate and explain my method Fair Test To ensure that this experiment is fair I will control the variables, i.
There are no anomalous results which shows that the experiment was very accurate. This is because as the temperature increases, the reactant particles move more quickly.
I did not have any problem whilst carrying out my investigation apart and do not believe I could have done it any better without specialist equipment with plenty of time.
My hypothesis was that quot;the reaction between sodium thiosulphate and acid will be fastest when the acid is at its Rate of Reaction — Sodium Thiosulphate and Hydrochloric Acid Category: This might have occurred for several different reasons, such as the fact that the temperature control might not have been exactly the same or that my judgement of when the cross may have disappeared might not have been exactly the same for each one.
Overall I think that my investigation was successful in obtaining reliable results. As the temperature increases the rate of reaction increases too, due to more collisions and more successful collisions, caused by the increase in temperature.
It also has a line of best fit to show the consistency and accuracy of the results. This means more of the particles collide and more of the collisions result in a reaction, so the rate of reaction increases. Evaluation All of my results were accurate and fitted the pattern of results.Chemistry rate of reaction coursework.
Chemistry Plan I am going to produce a piece of coursework investigating the rate of reaction, selecting a variable to see how this affects the rate. The rate of reaction is the rate of loss of a reactant or the rate of formation of a product.
Both the Sodium Thiosulphate and Hydrochloric acid are. GCSE CHEMISTRY RATES OF REACTION COURSEWORK. Anjelina Qureshi Mrs Gravell Rates of Reaction Coursework Chemistry Year 11 Rates of reaction Introduction A chemical reaction occurs when things change from reactants into products.
My hypothesis was that “the reaction between sodium thiosulphate and acid will be fastest when the acid is. Jul 02, · In this particular investigation I am going to find out how heat affects the rate of reaction in the reaction of sodium thiosulphate with hydrochloric acid.
Sulphur forms a colloidal precipitate which gives the solution a cloudy yellow appearance. The rate of reaction can be found by measuring the time for the solution to become mi-centre.coms: +Chemistry Coursework-How the concentration effects the rate of reaction between sodium thiosulphate and hydrochloric acid By Jess McFarlane 11WM Introduction Sodium thiosulphate and hydrochloric acid are two colourless solutions that gradually react together to form a cloudy yellow precipitate of sulphur when they are mixed.
