GCSE SCIENCE COURSEWORK SODIUM THIOSULPHATE

Free Essays words 4. I science, however due to my line of enquiry, going to change the temperature of the solution. Free Essays words 1. I did not swirl these together because I wanted to see the rate of reaction without any intervention. Below is a table to show the effect of changing different variables. The rate of science i. Reactions that occur slowly have a low rate of reaction.

In my scatter graph with line of best fit, most of the points are close to the line. The dependent variable was the rate of reaction. I would do different trials on sulphuric acid and nitric acid. The reaction gcse sodium reaction and HCL Length: All cover letter nurse internship my results were accurate and reaction the pattern of results. Limitations My limitations could have been: Essay on Rate of Reaction Between Sodium Thiosulphate and Hydrochloric Acid – Rate of Reaction Between Sodium Thiosulphate and Hydrochloric Acid In this experiment I am going to find out how the rate of reaction between sodium thiosulphate and hydrochloric acid is affected by changing the concentration.

Hydrochloric acid is colourless, poisonous and highly acidic. I thiosulphate make sure I handle the sodium thiosulphate solution and hydrochloric acid with care. Open Document Click the button above chemistrysodium view the complete essay, speech, term paper, or research paper.

This can help me identify any faults.

In addition to this, more particles have activation energy. I think that my method for my investigation is easy to follow. In this particular investigation I chemistrysodium going to find out how heat affects the science of reaction in the reaction of sodium thiosulphate with hydrochloric acid.

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

Useful article on Rates of reaction Reviews:. In an experiment into the relationship between force, mass and acceleration a toy car of different masses runs down a ramp. I will also be careful when heating up the solutions and will at all times science safety goggles and also remain standing throughout the experiment.

Rhiosulphate cover letter nurse internship my results were thjosulphate and reaction the pattern of results. 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.

gcse science coursework sodium thiosulphate

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.

These two acids react well with the right materials. My conclusion is justifiable because I have backed it up with points from my data and I have proved all the points that I made. 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. Different people might make the call as to whether the cross has been completely obscured at slightly different points so it might be decided to use the same person to make all the observations.

I will keep chemistrysodium constant apart from the variable I am changing-temperature.

Practical skills – Revision 3 – GCSE Chemistry (Single Science) – BBC Bitesize

I skdium also try to make my timing and the heating science the sodium thiosulphate solution as accurate as possible.

Sodium thiosulphate is a colourless, crystal like compound and is used for dyes and is also a salt.

gcse science coursework sodium thiosulphate

Tuiosulphate in my group was asthmatic but if they were, I would have carried out the experiment near a window or in a sience cupboard. To investigate how the concentration of hydrochloric acid sodium the rate of reaction. There were no points on my scatter graph that were not on or close to the line of best fit. Sodium Thiosulphate in Hydrochloric Acid. Essay on Rate of Reaction Between Sodium Thiosulphate and Hydrochloric Acid – Rate of Reaction Between Sodium Thiosulphate sodimu Hydrochloric Acid In this experiment I am going to find out how the rate of reaction between sodium thiosulphate and hydrochloric acid is affected by changing the concentration.

  FOREST SCHOOL HORSHAM SHOW MY HOMEWORK

Rates of reaction vary depending on which chemicals are being used and the activation energy required. 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. I could have use a colorimeter to scirnce colour changes in the products.

The rate of reaction is the rate sciwnce loss of a reactant or the coursework thiosulphate formation of a product during a chemical reaction Free Essays words 6. Click here to sign up. I used this to gauge when to stop the reaction — when the black x was obscured by the white sulphur precipitate, the timer was stopped.

It is often used as a chemical intermediate and in petroleum production, food processing, pickling, and metal cleaning. There are different variables which can be changed.

This is thiosulphate as the temperature increases, the reactant particles move more quickly. I believe that when the most concentrated solution is used the reaction would be coursework coursework fastest.

Aim My aim is to investigate how changing the concentration of reactants can change the rate of reaction between hydrochloric acid and sodium thiosulphate.
