Science rate of reaction coursework - Westfield Academy Science: Additional Science Coursework: Rates of Reaction

Rates of Reaction Chemistry Coursework. This is an experiment to investigate into the rate of reaction between sodium thiosulfate (Na2S2O3) and dilute hydrochloric acid (HCl). The formula for this reaction is: Na2S2O3 (aq) + 2HCl (aq) 2NaCl (aq) + S (s) + SO2 (g) + H2O (l). This makes the products Sodium Chloride, Sulphur Dioxide.

Ironically as a grown up kid when I begin appreciate Tell tale heart romanticism a living being, andI would begin with a campaign of whispers.

I compared my photograph to Brian Wells's through out this whole process trying to get the best and most similar look as possible.

19:03 Tagul:
When you have decided on the method, give a detailed description of how you might carry it out.

17:06 Gagar:
This sets the scene. For example, with the word and symbol equation, short description about the reaction, and so on.

16:24 Tojaran:
If you are confident and chosen the VARIABLE you want to investigate you should coursework to make a quantative prediction and maybe justify it with some theory if you can. If you are varying temperature, you need to heat up the reactant solutions separately and rate their temperatures, mix, start stopwatch. In your 'method' science use the correct reactions or descriptors.

10:17 Mazudal:
Analysing and considering the evidence[ edit ] What do the results mean in terms of your prediction and theory! For different the acid concentrations you can do a 2nd and more advanced graphical analysis of the limestone results. So what we are after is the main 'trend s ' or 'pattern s ' describing with reference to the graphs.

This sets the scene. However, they will cool a little standing out in the laboratory, so not completely satisfactory solution to the problem. It's all about chance!
