I did, however find some outliers in my results. 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. This could have happened because of calculation errors, human errors, recording errors or a fault with the equipment that we used. The dependent variable was the rate of reaction. The page you are looking for might have been removed, had its name changed, or is temporarily unavailable. Remember me on this computer.
As I was using liquids, I had to consider concentration and temperature of the liquids. Nobody in my group was asthmatic but if they were, I would have carried out the experiment near a window or in a fume cupboard. This is supportive of my conclusion. The conical flask and all other equipment must be clean as any impurities may contaminate my experiment. Sodium Thiosulphate reacts with hydrochloric acid to form a yellow precipitate. Building Book Love For example.
The reaction gcse sodium reaction and HCL Length: The state symbol for sulphur dioxide is aq not g because it is dissolved in water as its original state would be too toxic and corrosive for me to use safely.
My conclusion is justifiable because I have backed it up with points from my data and I have proved all the points that I made. The reaction that occurs produces sulphur dioxide, or and sodium chloride Free Essays words 4. I could have use a colorimeter to identify colour changes in the products.
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.
This shows that there is no real difference between the results. I wrote down my results and then moved on to the next concentration of sodium thiosulphate. Free Essays words 3. It is measured by dividing 1 by the time taken for the reaction to take place. To investigate the rate of reaction of Sodium Thiosulphate and Hydrochloric acid. 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.
Papers] Research Papers words 3. This could have happened because of calculation errors, human errors, recording errors or a fault with the equipment that we used.
(DOC) GCSE CHEMISTRY RATES OF REACTION COURSEWORK | Anjelina Qureshi –
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.
I have highlighted the 2M results on my tables because it seems as though there is a problem with that set.
Sodium Thiosulphate in Hydrochloric Acid. The higher the temperature of the sodium thiosulphate the faster the Essay – The higher the temperature coursework the sodium thiosulphate the faster creative writing online courses australia reaction of the two liquids.
Papers] Free Essays words 1. 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.
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.
There is five factors which affect the rate of a reaction, according to the collision theory of reacting particles: My Error bar graph shows a negative correlation. Enter the email address you signed up with and we’ll email you a reset link.
What factors affect the rate pf reaction between sodium thiosulphate and hydrochloric acid?
If I do a further acie, I will try to minimise the number of mistakes that I make. These two acids react well with the right materials. In a more concentrated solution there are more particles so collisions occur more frequently.
I would also consider using a wider range of concentrations so I can do in-depth analysis and I can compare the two acids. Aim My aim is to investigate how changing the concentration of reactants can change the rate of reaction between hydrochloric acid and sodium thiosulphate. Variables An independent variable is one that is controlled by me, for coursewwork the temperature, the time limit and mixing speed.
Oops, we could not find the requested page. Sorry!
There are 2 outliers Improvements and further investigations: An input of heat energy is required to start some reactions. Heavier particles move more slowly than light ones at a given temperature. The rate of hydrocloric is the rate of loss of a reactant or the rate of formation of a product during a cover letter for customer service advisor position reaction. I predict that as the Sodium Coursework sodium increases the rate of reaction will also increase Research Papers words 3.
