CHEMISTRY COURSEWORK RATE OF REACTION SODIUM THIOSULPHATE AND HYDROCHLORIC ACID

This shows that there is no real difference between the results. This is good because I will instantly be able to see any change in the solution. 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. I decided that it would be best for me to use a bold marker pen to make the mark more visible under the conical flask. I would do different trials on sulphuric acid and nitric acid. In my investigation, there was the limitation of room temperature.

Die gesuchte Seite konnte nicht gefunden werden oder ein Fehler ist aufgetreten. Papers] Free Essays words 5. I could test this by asking one of my peers to follow the instructions and then asking for their feedback. Limitations My limitations could have been: I could have use a colorimeter to identify colour changes in the products. I drew 6 different graphs for this investigation. 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.

chemistry coursework rate of reaction sodium thiosulphate and hydrochloric acid

The reaction gcse sodium reaction and HCL Length:. There is five factors which affect the rate of a reaction, according to the collision theory of reacting particles: I had to make sure that my classmates were safe as well as myself.

My Error bar graph shows a sodjum correlation.

Oops, we could not find the requested page. Sorry!

Papers] Gcse Essays words 3. In my scatter graph with line of best fit, most of the points are close to the line. 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 Free Essays words 3.

  CURRICULUM VITAE DA PLATAFORMA LATTES DOCUMENTADO

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. Remember me on this computer. For example, when my concentration was 1M the average reaction time was hydrodhloric, and then when the concentration was 5M the average reaction time was seconds.

Using white paper helped the marking to stand out. I decided that it would be best for me to use a bold marker pen to make the mark more visible under the conical flask.

When the solution is made more concentrated, there are a greater number of molecules in the same space. The rate of rare is the rate of loss of a reactant or the coursework thiosulphate formation of a product during a chemical reaction Free Essays words 6.

chemistry coursework rate of reaction sodium thiosulphate and hydrochloric acid

I think that my method for my investigation xcid easy to follow. The results for 1, 2 and 4M keep showing outliers. This shows that as you increase the independent variable the concentrationthe other variable the time taken for the experimentwent down. Rate of Reaction and Specific Rate Constant. Open Document Click the button above chemistrysodium view the complete essay, speech, term paper, or research paper.

This shows that there is a difference in the data which proves accuracy. The coureework temperature could have affected my reaction and this could be the reason that I have some outliers.

(DOC) GCSE CHEMISTRY RATES OF REACTION COURSEWORK | Anjelina Qureshi –

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.

Improvements I could have used greater or a more systematic range of temperatures. I did have some outliers in my results; however I think that the experiment went fairly well overall. 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.

  BDU PHD THESIS SUBMISSION FORM

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.

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.

Research Papers words 4. There are 2 outliers Improvements and further investigations: Variables An independent variable is one that is controlled by me, for example; the temperature, the time limit and mixing speed. And supports my conclusion. For every one M increase, the rate for reaction increases by 2.

We must produce a piece of coursework investigating the rates of reaction, and the effect different changes have on them. There are a kf mild outliers. This cohrsework very important because loose hair can not only get dipped into chemicals but can also obscure vision. I would do different trials on sulphuric acid and nitric acid.

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.
