Keep the size of my measuring flask is the same size; this should hopefully make my experiment much fairer and accurate. When coursework temperature is increased around or on these particles, the faster they move. I will be timing and watching: 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. Background Research Chemical reactions are to do with changing the materials that form the base of your experiment. I did, however find some outliers in my results.
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. There are a few mild outliers. I did not swirl these together because I wanted to see the rate of reaction without any intervention. Using white paper helped the marking to stand out. The conical flask and all other equipment must be clean as any impurities may contaminate my experiment. I would do different trials on sulphuric acid and nitric acid.
Building Book Love For example. 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. The reaction that occurs produces sulphur dioxide, water and sodium chloride. Help Center Find new research papers in: The reaction between sodium thiosulphate and HCL.
Rate of Reaction – Sodium Thiosulphate and Hydrochloric Acid
For every one M increase, the rate for reaction increases by 2. I would also consider using a wider range of concentrations so I can do in-depth analysis and I can compare the two acids. To investigate the rate of reaction of Sodium Thiosulphate and Hydrochloric acid.
My data was precise because most of the points on my graphs are close to the line and are all close by each other. My Error bar graph shows a negative correlation. 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. 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.
I did not swirl these together because Deaction wanted to see the rate of reaction without any intervention. This theory defines the differences between solids liquids and gasses; in a coureswork 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. Papers] Free Essays words 5.
The equation to this is as follows: The rate of reaction is the speed of a reaction. Science Experiments Coursework Rates Ciursework. Reactions that happen quickly have a high rate of reaction.
Dependent variables are not controlled by the experimenter.
Oops, we could not find the requested page. Sorry!
In this investigation I thkosulphate be varying the concentration of Sodium Thiosulphate thesis writing practice worksheets and not the Hydrochloric acid concentration. Evaluation – My gcse are reliable because I made it a fair test. My conclusion is valid because it includes evidence that my data is accurate and I have summed up my experiment in it.
I had to make sure that my classmates were safe as well as myself. I am investigating the different factors which may speed up chemical reactions.
In my scatter graph with line of best fit, most of ckursework points are close to the line. For example, rusting is a slow reaction; it has a low rate of reaction.
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.
The bars for 3M, 4m thiossulphate 5M do not overlap.
(DOC) GCSE CHEMISTRY RATES OF REACTION COURSEWORK | Anjelina Qureshi –
The bars of 1M and 2M overlap and this shows that there is no real difference. Sodium thiosulphate is a colourless, crystal like compound and is used for dyes and is also coursweork salt. I coursewoek test this by asking one of my peers to follow the instructions and then asking for their feedback. My data was quite accurate because all of my data follows a particular pattern and the points are all close together.
This is very important because loose hair can not only get dipped into chemicals but can also obscure vision. When coursework temperature is increased around or on these particles, the faster they move. This shows that there is a difference in the data which proves accuracy.
