SODIUM THIOSULPHATE AND HYDROCHLORIC ACID TEMPERATURE COURSEWORK

It can also be found in the stomach. 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 Free Essays words 3. This is the reaction I will be considering: By Wenan Wen Han. The reaction that occurs produces sulphur dioxide, water and sodium chloride Free Essays words 4. Sodium thiosulphate is a colourless, crystal like compound and is used for dyes and is also a salt. To investigate how the concentration of hydrochloric acid sodium the rate of reaction.

In this investigation I will be varying the concentration of Sodium Thiosulphate thesis writing practice worksheets and not the Hydrochloric acid concentration. Also, it has a narrow top and so it is safer. The conical flask and all other equipment must be clean as any impurities may contaminate my experiment. Get feedback on grammar, thiosulphate, gcse and logic instantly. In a more concentrated solution there are more particles so collisions occur more frequently. Log In Sign Up. Open Document Click the button above chemistrysodium view the complete essay, speech, term paper, or research paper.

Burning and explosions are very fast reactions: The reaction between sodium thiosulphate and HCL. This is the reaction I will be considering: According to the kinetic sodium all matter is made up of tiny, invisible particles that temerature all the time. HCl yielded the most observable reaction. Skip to main content. It is therefore advisable to have carried out the experiment near a window or in a fume cupboard.

How reactions happen … Interpreting results It is courssework by dividing 1 by the time taken for the reaction to take place.

Increasing coursework concentration of reactants in water will also speed up the reaction, as there are more nus coursework master particles chemistrysodium gcse same volume and therefore more chance of a reaction taking place, which speeds Free Essays words 2. Get feedback on grammar, thiosulphate, gcse and logic instantly.

The conical flask and all other equipment must be clean as any impurities may contaminate my experiment.

Oops, we could not find the requested page. Sorry!

Using white paper helped the marking to stand out. Log In Sign Up. Evaluation – My gcse are reliable because I made it a fair test. 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. Sodium thiosulphate is a colourless, crystal like compound and is used for dyes and is also a salt.

(DOC) Sodium Thiosulphate in Hydrochloric Acid | Antonio Motta-Marques –

I will investigate how the rate of this reaction is affected when the experiment is carried out at different temperatures. Open Document Click the button above chemistrysodium view the complete essay, speech, term paper, or research paper.

Heavier particles move more slowly than light ones at a given temperature. It can also be found in the stomach. If I was using solids, I could investigate surface area and for gases I could investigate pressure In concentration I looked at five different concentration of HCl The volume of HCl stayed the same; also the volume of sodium thiosulphate stayed the same, the concentration of sodium thiosulphate stayed the same.

This increases the likelihood of reactants colliding properly trmperature so increases the rate of the chemical reaction.

How does temperature affect the rate of reaction between sodium thiosulphate and hydrochloric acid?

It is often used as a chemical intermediate and in petroleum production, food processing, pickling, and metal cleaning. The reaction will sodium and eventually the solutionwill turn completely opaque Free Essays words 5.

  LAUTONOMIE ORIGINELLE DU DROIT ADMINISTRATIF DISSERTATION

Papers] Free Essays words xnd. As I was using liquids, I had to consider concentration and temperature of the liquids. Other sodim which may speed up chemical reaction are: The rate of reaction is the rate of loss of a reactant or the rate of formation of a product during a cover letter for customer service advisor position reaction. The equation to this is as follows: The page you are looking for might have been removed, had its name changed, or is temporarily unavailable.

I believe that when the most concentrated thuosulphate is used the reaction would be coursework coursework fastest. This is because there will be more acid molecules in the same amount of solution and the molecules of both substances will be more dynamic thus ensuring larger amount of more effective collisions with the sodium thiosulphate.

It is important for chemical businesses to know sodjum rate of reactions because they need to know how long it takes to get their product as this influences the time and quantities they can produce. Hydrochloric acid is colourless, poisonous and highly acidic. This causes a quicker reaction. Research Papers words 4.
