I have used reliable resources to research this information and it all confirms my conclusion. The room temperature could have affected my reaction and this could be the reason that I have some outliers. Papers] Gcse Essays words 3. This is good because I will instantly be able to see any change in the solution. Enter the email address you signed up with and we’ll email you a reset link.
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. For every one M increase, the rate for reaction increases by 2. 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. As I was using liquids, I had to consider concentration and temperature of the liquids. 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:
The reaction between sodium thiosulphate and HCL. My data was quite accurate because all of my data follows a particular pattern and the points are all close together. Sodium hydrochlorix is a colourless, crystal like compound and is used for dyes and is also a salt.
Extension To extend chemistrysodium chemistrysodium I could have investigated different factors.
If you contact us after hours, we’ll get back to you in 24 hours or less. On my ROR graph, there is a positive correlation. This ensures that the solution is completely opaque when I stop the timer. I tied my hair back, tucked in my tie and pushed all stools and bags under the desk where there is no risk of anyone tripping.
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 think this because there is outliers in the 2M set of data and the error bars overlap between 1M and 2M on my error bar graph. This theory defines the differences between solids liquids and gasses; in a gas 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.
Reactions that happen quickly have a high rate of reaction. I did have some outliers in my results; however I think that the experiment went fairly well overall. I have used reliable resources to research this information and it all confirms my conclusion. 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.
I would do different trials on sulphuric acid and nitric acid. I will discuss these further in my ahd. I predict that as the concentration of the Sodium Thiosulphate doubles, the rate of the reaction will double.
Investigating the rate of reaction between sodium thiosulphate and hydrochloric acid
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.
I tucked in my tie and shirt, and took off my blazer. I drew 6 different graphs for this investigation. Help Center Find new research papers in: 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.
The rate of reaction between sodium thiosulfate and hydrochloric acid. Abd energy gives the reactant particles enough energy to collide with enough force to break apart the bonds so that new products can be made from atoms.

Sodium Thiosulphate + Hydrochloric Acid Coursework – GCSE Science – Marked by
Rates of reaction vary depending on which chemicals are being used and the activation energy required. It can also be found in the stomach. My data was precise because most of the points on my graphs are close to the line and are all close by each other.
This increases the likelihood of reactants colliding properly and so increases the rate of the chemical reaction. These two acids react well with the right materials.
I will investigate how the rate of this reaction is affected when the experiment is carried out at different temperatures.
