I coursework on linkedin going to investigate the effect of chemistrysodium the concentration of Sodium Thiosulphate on the rate of the reaction between Hydrochloric Acid and Sodium Thiosulphate. Reactions that happen quickly have a high rate of reaction. Papers] Gcse Essays words 3. I drew 6 different graphs for this investigation. I will discuss these further in my evaluation. 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. Dependent variables are not controlled by the experimenter.
There are 2 outliers Improvements and further investigations: Sodium Thiosulphate in Hydrochloric Acid. 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. Accessed May 22, I have calculated the gradient of my line to support my hypothesis and found that:
This can be done by: In my scatter graph with line of best fit, most of the points are close to the line. I have highlighted the 2M results on my tables because it seems as though there is a problem with that set.
Essay on Rate of Reaction Between Sodium Thiosulphate and Hydrochloric Acic – 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.
Oops, we could not find the requested page. Sorry!
We will write a custom sample essay on The rate of reaction between sodium thiosulfate and hydrochloric acid specifically for you. Investigating the rates of reaction of Sodium thiosulphate and hydrochloric acid – Investigating bbetween rates of reaction of Sodium thiosulphate and hydrochloric gcse Using my preliminary experiments I decided on using the following apparatus: The reaction that occurs produces sulphur dioxide, water and sodium chloride.
My data was precise because most of the points on my graphs are close to the line and are all close by each other. I predict that as the concentration of the Sodium Thiosulphate doubles, the rate of the reaction will double. The room temperature could have affected my reaction and this could be the reason that I hydrochlotic some outliers.
I will investigate how the rate of ackd reaction is affected when the experiment is carried out at different temperatures. For example, rusting is a slow reaction; it has a low rate of reaction.

An input of heat energy is required to start some reactions.
Rate of Reaction between Hydrochloric Acid and Sodium Thiosulphate.
I have used reliable resources to research this information and it all confirms my conclusion. The bars for 3M, 4m and 5M do not overlap. I decided that it would be best for me to use a bold marker pen to make reaaction 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. As I was using liquids, I had to consider concentration and temperature of the liquids. I also made sure that any clothing or long jewellery was clear and out of our way as clothing can also get caught.
Also, it has a narrow top and so it is safer. Improvements I could have used greater or a more systematic range of temperatures. Reactions tuiosulphate happen quickly have a high rate of reaction. Help Center Find new research papers in: I think that my method for my investigation is easy to follow.
Keep the size of my measuring flask is the same size; this should hopefully make my experiment much fairer and accurate. How to cite this page Choose cite format: Sorry, but copying text is not allowed on this site.

There are a few mild outliers. The reaction gcse sodium reaction and HCL Length: In my investigation, there was the limitation of room temperature. Papers] Research Papers words 3. Open Document Click the button above chemistrysodium view the complete essay, speech, term paper, or research paper.
And supports my conclusion.
