It is measured by dividing 1 by the time taken for the reaction to take place. These chemicals are perfect for my investigation because they are both clear and colourless. This can help me identify any faults. Oops, we could not find the requested page.
On my ROR graph, there is a positive correlation. If I was using solids, I could investigate surface area and for gases I could investigate pressure In concentration I looked at five different concentration of HCl The volume of HCl stayed the same; also the volume of sodium thiosulphate stayed the same, the concentration of sodium thiosulphate stayed the same. When the solution is made more concentrated, there are a greater number of molecules in the same space. 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. Conclusion In my investigation, my data and my graphs proved that my hypothesis was correct.
There is one outlier in 2M concentration. For example, when my concentration was 1M the average reaction time was seconds, and then when the concentration was 5M the average reaction time was seconds. The results for 1, 2 and 4M keep showing outliers. This is the reaction I will be considering: We’ll occasionally send you account related and promo emails.
The size of the error bars is quite small so I think Recation can say that my data is quite accurate except for the 2M result which is quite a long error bar. Hi there, would you like to get such a paper? Improvements I could have used greater or a more systematic range of temperatures.
If you need this or any other sample, we can send it to you via email.
Essay on Rate of Reaction Between Sodium Thiosulphate rae 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.
Extension To extend chemistrysodium chemistrysodium I could have investigated different factors.
To do this I would make sure that: The page you are looking for might have been removed, had its name changed, or is temporarily unavailable. Evaluation – My gcse are reliable because I made it a fair test. How about make it original? Evaluation My coureework deviation sheet is attached at the back of this document marked with an asterisk.
Rate of Reaction – Sodium Thiosulphate and Hydrochloric Acid Coursework
My conclusion is valid because it includes evidence that my data is accurate and I have summed up my experiment in it. Click chemistry button above to view the complete essay, speech, term paper, or research paper.
The bars of 1M and 2M overlap and reactioon shows that there is no real difference. I then drew up graphs for my results Data Concentration Test Test 2 Test 3 M 1 s s s 1 2 3 4 5 Table 1: Thioulphate My limitations could have been: This could have happened because of calculation errors, human errors, recording errors or a fault with the equipment that we used.
This is because when there are more molecules in the solution, there reactikn more molecules to collide so ahd will speed up the reaction, and therefore it is more likely they will collide with each other.
These reactions only happen if the reacting molecules collide properly. This shows that my data is quite accurate. Rate of Reaction and Specific Rate Constant. Using white paper helped the marking to stand out. I made sure that I had everything before I started.

In a more concentrated solution there are more particles so collisions occur more frequently.

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. This can help me identify any faults.
The points in the top right are quite coursewlrk down so this shows a negative correlation. 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.
