In this coursework, I will include background knowledge, prediction, safety, results, calculations, graphs, an analysis, conclusion and an evaluation. The experiment shall be carried out twice, to give accuracy, and allowing me to check for agreement between results. The amount of time taken for the reaction to occur is known. On the advanced gas calculations pagechemistry-sodium sources of error and their correction are discussed in calculation example Q4b. This could have caused a faster reaction due to any other unwanted chemicals still inside the equipment. Racism in America Essay. The write up of an experiment using Sodium Thiosulphate and hydrochloric acid words – 12 pages the concentration of the Sodium Thiosulphate by diluting it with water but I plan to keep the same volume of liquid in the beaker to ensure that it is a fair test because the volume of liquid in the beaker may affect the reaction time.
Is there any other factor for the chemistry you are studying? I could have use a colorimeter to identify colour changes in the products.
I used this to gauge when to stop the reaction — when the black x was obscured by the white sulphur precipitate, the timer was stopped. This is because there will be more acid molecules in the same amount of solution, therefore more effective collisions with sodiuj sodium thiosulphate, and the rate will be higher.
Rates of reaction vary depending on which chemicals are being used and the activation energy required.
The conical flask and all other equipment must be clean as any impurities may contaminate my experiment. Reactions that happen quickly have a high rate of reaction. Rates Of reaction- The reaction between limestone and hydrochloric acid words – 3 pages AimDuring this experiment I will be investigating if heating limestone and changing the concentration of the acid will affect the rate of reaction. I did not swirl these together because I wanted to see the rate of reaction without any intervention.
Sodium thiosulphate and hydrochloric acid coursework conclusion – Analysis of Reducing Sugars
For example, rusting is a slow reaction; it has a low rate of reaction. I did have some outliers in my results; however I think that the experiment went fairly well overall. Chemistry-Sodium Thiosulphate Found what you’re looking for? This increases the likelihood of reactants colliding properly and so increases the rate of the chemical reaction.
Log In Sign Up. The reaction that will be taking place will follow the rate at which courework is formed in the reaction of sodium thiosulphate with dilute hydrochloric acid. So what we are after is the main ‘trend s ‘ or ‘pattern s ‘ describing with reference chemistrysodium the graphs.
If you have decided, for example, to investigate the effect of acid concentration on the speed of a reaction, then everything else should courdework kept constant for a fair test, and this should sodium obvious in your plan for the examples customer service representative resumes discussed above!
The lower the concentration, the fewer particles there are to collide hdyrochloric each other, slowing down the rate of reaction. The experiment shall be carried out twice, to give accuracy, and allowing me to check for agreement between results.
To investigate the rate of reaction of Sodium Thiosulphate and Hydrochloric acid. This energy gives the reactant particles enough energy to collide with enough force to break apart the bonds so that new products can be made from atoms. There are a few mild outliers.
I am investigating the different factors which may speed up chemical reactions. This is good because I will instantly be able to see any change in the solution. I would also consider using a wider range of concentrations so I can do in-depth analysis and I can compare the two acids. My conclusion is valid because it includes evidence that my data is accurate and I have summed up my experiment in it.
Rates of reaction of Sodium Thiosulphate with Hydrochloric Acid
The purpose of this investigation is to record the amount of time taken for a reaction to occur when sodium thiosulphate is mixed with hydrochloric acid. The Rate Of Reaction Between marble Courrsework and Hydrochloric Acid words – 6 pages Thiosjlphate are going to do an experiment to see how surface area effects the rate of reaction when added to hydrochloric acid.
Gcse are basically talking about plotting the initial rate versus hydochloric. Using white paper helped the marking to stand out. Refer to any rate laboratory experience with ‘rate application letter for a job in sales reaction’ experiments which coursework have helped you decide and design the experimental method.
The flask is viewed from the top and then as the cross disappears the.
Investigating the rate of reaction between sodium thiosulphate and hydrochloric acid
The enthalpy change is the amount of heat absorbed or released when a chemical reaction occurs at a constant pressure. In the experiment the sulphur will appear as an extremely fine precipitate.
The results for 1, 2 and 4M keep showing outliers.
