Help Center Find new research papers in: 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. This causes a quicker reaction. I think that my method for my investigation is easy to follow. Dependent variables are not controlled by the experimenter.
This increases the likelihood of reactants colliding properly and so increases the rate of the chemical reaction.
The reaction between Sodium Thiosulphate and Hydrochloric Acid.
Die gesuchte Seite konnte nicht gefunden werden oder ein Fehler ist aufgetreten. Reactions that occur slowly have a low rate of reaction.
Papers] Free Essays words 5. The rate of reaction between sodium thiosulfate and hydrochloric acid. 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.
These two acids react well with the right materials. Hypothesis My prediction is that the reaction between sodium thiosulphate and acid will be fastest when the acid is at its highest concentration. The state symbol for sulphur dioxide is aq not g because it is dissolved in water as its original thiosulpahte would be too toxic and corrosive for me to use safely. The reaction aid sodium and eventually the solutionwill turn completely opaque Free Essays words 5.
Oops, we could not find the requested page. Sorry!
Also, it has a narrow top and so uydrochloric is safer. This shows that my data is quite accurate. The rate of reaction is the speed of a reaction.
The reaction gcse sodium reaction and HCL Length:. I will be timing and watching: This is the reaction I will be considering: Sodium thiosulphate is a colourless, crystal like compound and is used for dyes and is also a salt.
Free Essays words 3. Conclusion In my investigation, my data and my graphs proved that my hypothesis was correct. Science Experiments Coursework Rates Essays]. 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 coirsework particles only coursework around fixed sodium and in liquids the particles have some freedom and can move around each other Free Essays words 3.
I tucked in my tie and shirt, and took off my blazer. When coursework temperature is increased around or on these particles, the faster they move. The reaction between sodium thiosulphate and HCL. This makes sure that coursewrok experiment runs smoothly.
How to cite this page Choose cite format: I drew 6 different graphs for this investigation. My data was quite accurate because all of my data sodim a particular pattern and the points are all close together. I believe that when the most concentrated solution is used the reaction would be coursework coursework fastest.
(DOC) GCSE CHEMISTRY RATES OF REACTION COURSEWORK | Anjelina Qureshi –
Click to learn more https: And supports my conclusion. Improvements I could have used greater or a more systematic range of temperatures.
I have used reliable resources to research this information and it all confirms my conclusion. I stood up to allow more space for others to walk by between the rooms. Background Knowledge The thiosulphate of a reaction can be speeded up by increasing the temperature; at a thiosulphare gcse the thiosuplhate move faster and collide more often, as a result of this the reaction speeds up.
My conclusion is valid because it includes evidence that my data is accurate and I have summed up my experiment in it.
