Building Book Love For example. Free Essays words 4. I made sure that I had everything before I started. Rates of reaction vary depending on which chemicals are being used and the activation energy required. I wrote down my results and then moved on to the next concentration of sodium thiosulphate.
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. Papers] Free Essays words 1. AS Inorganic Chemistry Titration. Sodium thiosulphate coursework writing is a really complicated task? There is one outlier in 2M concentration. 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. Ict ocr a secondary data for approval by ocr gcse coursework.
This good because it shows that for every increase in concentration is a decrease in rate of reaction.
This shows that there is no real difference between the results. Research Papers words 4.

Gcse sodium doursework coursework. 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. To investigate the effect of.
The points in the top right are quite far down so this shows a negative correlation.
Background Knowledge The thiosulphate of a reaction can be speeded up by increasing the temperature; at a higher gcse the particles cousework faster and collide more often, as a result of this the reaction speeds up. 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: Reaction of sodium thiosulphate and hydrochloric acid. Reactions that occur slowly have a low rate of reaction. Se technology and design coursework! This shows that there is a difference in the data which proves accuracy.
Gcse sodium thiosulphate coursework
Improvements I could have used greater or a more systematic range of temperatures. I also made sure that the measuring cylinder was on a level surface so that I could clearly see how much liquid I was putting in to it. Heavier particles move more slowly than light ones at a given temperature.
I have used reliable resources to research this information and it all confirms my conclusion. To investigate the rate of reaction of Sodium Thiosulphate and Hydrochloric gces.
When the solution is made more concentrated, there are a greater number of molecules in the same space. Enter the email address you signed up with and we’ll email you a reset link. The reaction that occurs produces sulphur dioxide, chemixtry and sodium chloride Free Essays words 4. Keep the size of my measuring flask is the same size; this should hopefully make my experiment much fairer and accurate.
