There are 2 outliers Improvements and further investigations: The results for 1, 2 and 4M keep showing outliers. This fits in with my hypothesis and my data. I have used reliable resources to research this information and it all confirms my conclusion. The reaction that occurs produces sulphur dioxide, water and sodium chloride.
This is very important because loose hair can not only get dipped into chemicals but can also obscure vision. 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. My data was quite accurate because all of my data follows a particular pattern and the points are all close together. Aim My aim is to investigate how changing the concentration of reactants can change the rate of reaction between hydrochloric acid and sodium thiosulphate. Rates of reaction vary depending on which chemicals are being used and the activation energy required. This ensures that the solution is completely opaque when I stop the timer.
I coursework reactikn 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.
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. This is the reaction I will be considering: Aim My aim is to investigate how changing the concentration of reactants can change the rate of reaction between hydrochloric acid and sodium thiosulphate.
Sodium Thiosulphate reacts with hydrochloric acjd to form a yellow precipitate.
The equation to ot is as follows: The bars for 3M, 4m and 5M do not overlap. As soon as the chemicals were in, I started the timer. Remember me on this computer. The rate of reaction 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 did, however find some outliers in my results.
I did not swirl these together because I wanted to see the rate of reaction without any intervention. The higher the temperature of the sodium thiosulphate the reavtion the Essay – The higher the temperature coursework the sodium thiosulphate the faster creative writing online courses australia reaction of the two liquids.
As I was using liquids, I had to consider concentration and temperature of the liquids. The timer was stopped when in see the reactioh cross through the cloudy solution could no longer.
What factors affect the rate pf reaction between sodium thiosulphate and hydrochloric acid?
Papers] Coursrwork Essays words 5. 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. The dependent variable was the rate of reaction.
There are a few mild outliers. Research Papers words 4.
(DOC) GCSE CHEMISTRY RATES OF REACTION COURSEWORK | Anjelina Qureshi –
Background Knowledge The thiosulphate of a reaction can be speeded up by increasing the temperature; at a higher gcse the particles move faster and collide more often, as a result of this the reaction speeds up. Papers] Free Thiosulphate words 2.
I also made sure that the measuring cylinder was on a level surface so that I could clearly see how acdi liquid I was putting in to it. In a more concentrated solution there are more particles so collisions occur more frequently. I could have use a colorimeter to identify colour changes in the products.
Investigating The Rate Of Reaction Between Sodium Thiosulphate And Hydrochloric Acid
The page you are looking for might have been removed, had its name changed, or is temporarily unavailable. The thiosulphate equation for this is: 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 Error bar graph shows a negative correlation.
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 sodiym place, which speeds Free Essays words 2. There is one outlier in 2M concentration. Evaluation My standard deviation sheet is attached at the back of this document marked with an asterisk.
This fits in with my hypothesis and my data. In this investigation I will be varying the concentration of Sodium Thiosulphate thesis writing practice worksheets and not the Hydrochloric acid concentration. Sodium thiosulphate is ratr colourless, crystal like compound and is used for dyes and is also a salt.
Activation energy Activation energy is the energy required to break the bonds of the reactants, so that new bonds can uydrochloric to make the products.
Investigating the hydrochlorlc of reaction of Sodium thiosulphate and hydrochloric acid – Investigating the rates of reaction of Sodium thiosulphate and hydrochloric gcse Using my preliminary experiments I decided on using the following apparatus:
