RATE OF REACTION COURSEWORK SODIUM THIOSULPHATE AND HYDROCHLORIC ACID

I would do different trials on sulphuric acid and nitric acid. I could test this by asking one of my peers to follow the instructions and then asking for their feedback. Die gesuchte Seite konnte nicht gefunden werden oder ein Fehler ist aufgetreten. Conclusion In my investigation, my data and my graphs proved that my hypothesis was correct. On my ROR graph, there is a positive correlation. Also, it has a narrow top and so it is safer. 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.

I drew 6 different graphs for this investigation. This is because there will be more acid molecules in the same amount of solution, therefore more effective collisions with the sodium thiosulphate, and the rate will be higher. This theory defines the differences between solids liquids and gasses; in a gas the particles move freely and at random in all the space available, in solids particles only coursework around fixed sodium and in liquids the particles have some freedom and can move around each other Free Essays words 3. I would do different trials on sulphuric acid and nitric acid. 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. There is five factors which affect the rate of a reaction, according to the collision theory of reacting particles: Use of rate of reaction in industry The chemical industry makes medicine and many other substances such as; Limestone – this is used for building Sulphuric acid — used to make other substances Ammonia – used to make fertilisers.

This is because there will be more acid molecules in the same amount of solution, therefore more effective collisions with the sodium thiosulphate, and the rate will be higher.

Oops, we could not find the requested page. I would do different trials on sulphuric acid and nitric acid. The independent variables in our experiment are the concentration of hydrochloric acid. The reaction that occurs produces sulphur dioxide, water and sodium chloride Free Essays words 4.

rate of reaction coursework sodium thiosulphate and hydrochloric acid

Limitations My limitations could have been: 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. I did not swirl these together because I wanted to see the rate of reaction without any intervention.

This causes a quicker reaction. I coursework on linkedin going to investigate the effect of chemistrysodium the concentration of Sodium Thiosulphate on the rate of the reaction between Hydrochloric Acid and Sodium Thiosulphate. I believe that when the most concentrated solution is used the reaction would be coursework coursework fastest.

Rate of Reaction – Sodium Thiosulphate and Hydrochloric Acid

Rate of Reaction sodijm Specific Rate Constant. Research Papers words 4. The thiosulphate equation for this is: Hydrchloric My standard deviation sheet is attached at the back of this document marked with an asterisk. I made sure that I had everything before I started.

I have calculated the gradient of my line to support my hypothesis and found that: I have used reliable resources to research this information and it all confirms my conclusion.

I predict that as the concentration of the Sodium Thiosulphate doubles, the rate of the reaction will double.

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 could have happened because of human error, wrong calculations or simply not enough activation energy on that particular concentration. Activation energy Activation energy is the energy required to break the bonds of the reactants, so that new bonds can form to make the products.

Conclusion In my investigation, my data and my graphs proved that my hypothesis was correct. According to the thiosulphxte sodium all matter or made up of tiny, invisible particles that move all the time.

I tucked in my tie and shirt, and took off my blazer. I will discuss these further in my evaluation.

Improvements I could have used greater or a more systematic range of temperatures. The conical flask and all other equipment must be clean as any impurities may contaminate my experiment. These reactions only happen if the reacting molecules collide properly.

This is good because I will instantly be able to see any change in the solution. Use of rate of reaction in industry The chemical industry makes medicine and many other substances such as; Limestone – this is used for building Sulphuric acid — used to make other substances Ammonia – used to make fertilisers.

Sodium Thiosulphate reacts with hydrochloric acid to form a yellow precipitate. The size of the error bars is quite small so I think I can say that my data is quite accurate except for the 2M result which is quite a long error bar.

I could test this by asking one of my peers to follow the instructions and then asking for their feedback. I wrote down my results and then moved on to the next concentration of sodium thiosulphate. 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.

And supports my conclusion.
