I could test this by asking one of my peers to follow the instructions and then asking for their feedback. These are circled on my graphs. The reaction between sodium thiosulphate and HCL. This shows that there is no real difference between the results. For example, when my concentration was 1M the average reaction time was seconds, and then when the concentration was 5M the average reaction time was seconds. As I was using liquids, I had to consider concentration and temperature of the liquids. Burning and explosions are very fast reactions:
This shows that as you increase the independent variable the concentration , the other variable the time taken for the experiment , went down. Science Experiments Coursework Rates Essays]. The independent variables in our experiment are the concentration of hydrochloric acid. Investigating the rates of reaction of Sodium thiosulphate and hydrochloric acid – Investigating the rates of reaction of Sodium thiosulphate and hydrochloric gcse Using my preliminary experiments I decided on using the following apparatus: It is often used as a chemical intermediate and in petroleum production, food processing, pickling, and metal cleaning. I did, however find some outliers in my results. According to the kinetic sodium all matter is made up of tiny, invisible particles that move all the time.
The rate of reaction is the rate of loss of a reactant or the coursework thiosulphate formation of a product during a chemical reaction Free Essays words 6. There are a few mild outliers. This ensures that the solution is completely opaque when I stop the timer.
The bars of 1M and 2M overlap and hyfrochloric shows that there is no real difference. The state symbol for sulphur dioxide is aq not g because it is dissolved in water as its original state would be too toxic and corrosive for me to use safely.
I am investigating the different factors rdaction may speed up chemical reactions. This shows that there is a difference in the data which proves accuracy. Die gesuchte Seite konnte nicht gefunden werden oder ein Fehler ist aufgetreten.
There is one outlier in 2M concentration. Conclusion In my investigation, my data and my graphs proved that my hypothesis was correct. Oops, we could not find the requested page. In a more concentrated solution there are more particles so collisions occur reactionn frequently Recent updates The rate of reaction is the rate of loss of a reactant or the coursework thiosulphate formation of a product during a chemical reaction Free Essays words 6.

It can also be found in the stomach. There is five factors which affect the rate of a reaction, according to the collision theory of reacting particles: I have highlighted the 2M results on my tables because it seems as though there is a problem with that set.
I did have some outliers in my results; however I think that the experiment went fairly well overall.
I did, however find some outliers in my results. 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. I will discuss these further in my evaluation.
To investigate the rate of reaction of Sodium Thiosulphate and Hydrochloric acid. As I was using liquids, I had to consider concentration and temperature of the liquids. The points in the top right are quite far down so this shows a negative correlation.
This 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.
The timer was stopped when in see the black cross through the cloudy solution could no longer. The reaction between sodium thiosulphate and HCL. This can help me identify any faults.
This thiksulphate in with my hypothesis and my data. I also made sure that the measuring cylinder was on a level surface so that I could clearly see how much liquid I was putting in to it.
Click chemistry button above to view the complete essay, speech, term paper, or research paper. 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.
Variables An independent variable is one that is controlled by me, for example; the temperature, the time limit and mixing speed.
I thiosulphatd be timing and watching: Activation energy Activation energy is the energy required to break the bonds of the reactants, so that new bonds can form to make the products. Papers] Free Thiosulphate words 2.
