RATE OF REACTION SODIUM THIOSULPHATE AND HYDROCHLORIC ACID COURSEWORK

The reaction that occurs produces sulphur dioxide, water and sodium chloride. Free Essays words 4. It can also be found in the stomach. If you need this or any other sample, we can send it to you via email. Open Document Click the button above chemistrysodium view the complete essay, speech, term paper, or research paper. Sorry, but copying text is not allowed on this site. Papers] Free Thiosulphate words 2.

This ensures that the solution is completely opaque when I stop the timer. Hydrochloric acid is colourless, poisonous and highly acidic. I am investigating the different factors which may speed up chemical reactions. I would do different trials on sulphuric acid and nitric acid. Heavier particles move more slowly than light ones at a given temperature. The equation to this is as follows: 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.

I then drew up graphs for my results Data Concentration Test Test 2 Test 3 M 1 s s s 1 2 3 4 5 Table 1: 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 solids particles only coursework around fixed sodium and in liquids the particles have some freedom and can move around each other.

This is because there will be more acid molecules in the same amount of solution, therefore more effective collisions with the sodium thiosulphate, and the rate will be higher. There is five factors which affect the rate of a reaction, according to the collision theory of reacting particles: The rate of reaction is the rate of loss thiosulphatd a reactant or the coursework thiosulphate formation of a product deaction a chemical reaction Free Essays words 6.

(DOC) GCSE CHEMISTRY RATES OF REACTION COURSEWORK | Anjelina Qureshi –

When anv solution is made more concentrated, there are a greater number of molecules in the same space. Sorry, but copying text is forbidden on this website! To investigate the rate of reaction of Sodium Thiosulphate and Hydrochloric acid.

rate of reaction sodium thiosulphate and hydrochloric acid coursework

Sodium Thiosulphate reacts with hydrochloric acid to form a yellow precipitate. This shows that as you increase the independent variable the concentrationthe other variable the time taken for the experimentwent down. This is supportive of my conclusion. Dependent variables are not controlled by the experimenter.

I will investigate how the rate of this reaction is affected when the experiment is carried out at different temperatures.

This can help me identify any faults. 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: There is one outlier in 2M concentration.

Rate of Reaction between Hydrochloric Acid and Sodium Thiosulphate.

In my investigation, there was the limitation of room temperature. I predict that as the concentration of the Sodium Thiosulphate doubles, the rate of the reaction will double. This ensures that the solution is completely opaque reactin I stop the timer. This shows that there is a difference in the data which proves accuracy.

In my scatter graph with line of best fit, most of the points are close to the line. If I was using solids, I could investigate surface area and for gases I could investigate pressure In concentration I looked jydrochloric five different concentration of HCl The hydrocjloric of HCl stayed the same; also the volume of sodium thiosulphate stayed the same, the concentration of sodium thiosulphate stayed the same. I predict that as the Sodium Coursework sodium increases the rate of reaction will also increase Research Papers words 3.

If you need this or any other sample, we can send it to you via email. This is good because I will instantly be able to see any change in the solution. My data was quite accurate because all of my data follows a particular pattern and the points are all close together.

Remember me on this computer. The rate of reaction between sodium thiosulfate and hydrochloric acid.

Reactions that occur slowly have a low rate of reaction. Papers] Free Thiosulphate words 2. And supports my conclusion.

rate of reaction sodium thiosulphate and hydrochloric acid coursework

I believe that when the most concentrated solution is used the reaction would be coursework coursework fastest.

I have used reliable resources to research this information tgiosulphate it all confirms my conclusion.

Rates of reaction of Sodium Thiosulphate with Hydrochloric Acid

Oops, we could not find the requested page. I decided that it would be best for me to use a bold marker pen to make the mark more visible under the conical flask. Extension To pf chemistrysodium chemistrysodium I could have investigated different factors.
