This shows that there is a difference in the data which proves accuracy. My data was precise because most of the points on my graphs are close to the line and are all close by each other. Reactions that happen quickly have a high rate of reaction. This is because when there are more molecules in the solution, there are more molecules to collide so this will speed up the reaction, and therefore it is more likely they will collide with each other. This makes sure that my experiment runs smoothly.
Evaluation – My gcse are reliable because I made it a fair test. The conical flask and all other equipment must be clean as any impurities may contaminate my experiment. Heavier particles move thiosulpphate slowly than light ones at a given temperature.
Oops, we could not find the requested page. Sorry!
Aim My aim is to investigate how changing the concentration of reactants can change the rate of reaction between hydrochloric acid and sodium thiosulphate. For every one M increase, the rate for reaction increases by 2.
My data has proven to be reliable and I am therefore happy to use it to make a justifiable conclusion that concentration does have an effect on rate of reaction.
If you contact us after hours, we’ll get back to you in 24 hours or less. I wrote down my results reacfion then moved on to the next concentration of sodium thiosulphate.
Bftween Research Chemical reactions are to do with changing the materials that form the base of your experiment. The reaction that occurs produces sulphur dioxide, water and sodium chloride Free Essays words 4.
I have highlighted the 2M results on my tables because it seems as though there is a problem with that set. The equation to this is as follows: I will discuss these further in my evaluation. We will write a custom sample essay on The yhiosulphate of reaction between sodium thiosulfate and hydrochloric reactuon specifically for you. The dependent variable was the rate of reaction. Sodium Thiosulphate in Hydrochloric Acid. Essay on Rate of Reaction Between Sodium Thiosulphate and Hydrochloric Acid – Rate of Reaction Between Sodium Thiosulphate and Hydrochloric Acid In this experiment I am going to find out how the rate of reaction between sodium thiosulphate and hydrochloric acid is affected by changing the concentration.
(DOC) GCSE CHEMISTRY RATES OF REACTION COURSEWORK | Anjelina Qureshi –
Increasing coursework concentration of reactants in water will also speed up the reaction, as there are more nus coursework master particles chemistrysodium gcse same volume and therefore more chance of a reaction taking place, which speeds Free Essays words 2. If I do a further investigation, I will try to minimise the number of mistakes that I make.
This ensures that the solution is completely opaque when I stop the timer. Dependent variables are not controlled by the experimenter. This shows hydgochloric my data is quite accurate. Click to learn more https: The room temperature could have affected my reaction and this could be the reason that I have some outliers.
My data was quite accurate because all of my data follows a particular pattern and the points are all close together.
Building Book Love For example. Limitations My limitations could have been: Click here to sign up. This makes sure that my experiment runs smoothly.
Burning and explosions are very fast reactions: It is often used as a chemical intermediate and in petroleum production, food processing, pickling, and metal cleaning.
For example, when my concentration was 1M the average reaction time was seconds, and then when the concentration coyrsework 5M the average reaction time was seconds.
In a more concentrated solution there are more particles so collisions occur more frequently Recent updates The rate of reaction is the rate of loss of a reactant or the coursework thiosulphate formation of a product during a chemical reaction Free Essays words 6. Skip to main content. This is because when there are more molecules in the solution, there are more molecules to collide so this will speed up the reaction, and therefore it is more likely they will collide with each other.
Sodium Thiosulphate reacts with hydrochloric acid to form a yellow precipitate. And supports my conclusion.
