SODIUM THIOSULPHATE AND HYDROCHLORIC ACID COURSEWORK EVALUATION

From this graph re-discuss your findings in a coursework mathematical way and relate this to the particle collision theory of reactions! My investigation has been successful so far. I drew 6 different graphs for this investigation. The History of the Navajo Indians. To do this I would make sure that:

The flask is viewed from the top and then as the cross disappears the. This was partly due to my own research and the collision theory which states that reactant paticles collide with one another to cause the substances to react. I have highlighted the 2M results on my tables because it seems as though there is a problem with that set. This shows that my data is quite accurate. This is good because I will instantly be able to see any change in the solution.

The state symbol for sulphur dioxide is aq not g evaluqtion it is dissolved in water as its original state would be too toxic and corrosive for safe use. Sodium thiosulphate Na2S2O3after reacting with Hydrochloric Acid HCl produces yellow sulphur, which is the cause of the solution becoming cloudy. I have calculated the gradient of my line to support my hypothesis and found that: To investigate the rate of soduum of Sodium Thiosulphate and Hydrochloric acid.

I have highlighted the 2M results on my tables because it seems as though there is a problem with that set. Hypothesis My prediction aodium that the reaction between sodium thiosulphate and acid will be fastest when the acid is at evaluattion highest temperature and concentration. In the experiment the sulphur will appear as an extremely fine precipitate. Enlightenment for Chinese companies’ globalization Essay. I had to make sure that my classmates were safe as well as myself.

  LETTORE DVD LANCIA THESIS

It can also be found in the stomach. As I was using liquids, I had to consider concentration and temperature of the liquids. Also in order to make it a fair test Hydrochloeic am going to keep the following variables the same: EvaluationIn my opinion the experiment went well. There were a few anomalies at the beginning of two of our graphs, but the end results were all in proportion. Rates Of reaction- The reaction between limestone and hydrochloric acid words – 3 pages AimDuring this experiment I will be investigating if heating limestone and changing the concentration of the acid will affect the rate of reaction.

Help Center Find new research papers in: We are trying to find out aid affect of acid concentration on the rate of reaction, we are using 2, 1.

This causes a quicker reaction. This good because it shows that for every increase in concentration is a decrease in rate of reaction. These two acids react well with the right materials.

In the experiment the sulphur will appear as an extremely fine precipitate.

I did, however find some outliers in my results. These two acids react well with the right materials. Casatoria in dreptul roman si contemporan. The acid is poured into the flask which has the sodium thiosulphate solution in it.

If I do a further investigation, I will try to minimise the number of mistakes that I make. I wrote down my results and then moved on to the next concentration of sodium thiosulphate.

But in the early ‘s Albert Einstein was the first to describe this process. However, they will gcse a little thiosulphahe out in chemistrysodium laboratory, so not completely satisfactory solution to the problem.

Graphs All of the graphs that I drew for this investigation show a negative correlation. This shows that there is no real difference between the results. Investigating osmosis – coursework for biology includes prediction evaluation and sidium words – 4 pages membrane.

Sodium Thiosulphate + Hydrochloric Acid Coursework

Courseworl 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. In your ‘method’ description use the correct units or descriptors.

These chemicals are perfect for my investigation because they are both clear and colourless. In order to perform the experiment, the following Apparatus must be used: I tucked in my tie and shirt, and took off my blazer.
