This 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 a more concentrated solution there are more particles so collisions occur more frequently. My data has proven to be reliable and I am therefore happy to use it to make a justifiable conclusion that concentration does have an effect on rate of reaction. Variables An independent variable is one that is controlled by me, for example; the temperature, the time limit and mixing speed. Papers] Free Essays words 1. The higher the temperature of the sodium thiosulphate the faster the Essay – The higher the temperature coursework the sodium thiosulphate the faster creative writing online courses australia reaction of the two liquids. I predict that as the concentration of the Sodium Thiosulphate doubles, the rate of the reaction will double.

I will investigate how the rate of this reaction is affected when the experiment is carried out at different temperatures. Building Book Love For example. When coursework temperature is increased around or on these particles, the faster they move. Hi, I am Sara from Studymoose Hi there, would you like to get such a paper? These are circled on my graphs. I also made sure that any clothing or long jewellery was clear and out of our way as clothing can also get caught. Evaluation – My gcse are reliable because I made it a fair test.

I stood up to allow more space for others to walk by between the rooms.

reaction between sodium thiosulphate and hydrochloric acid coursework

In a more concentrated solution there are more particles so collisions occur more frequently. 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 hydrochlofic around each other. This fits in with thjosulphate hypothesis and my data.

It can also be found in the stomach.

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

If you need this or any other sample, we can send it to you via email. Free Essays words 3. Hydrochloeic 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.

Sorry, but copying text is not allowed on this site. Adn 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.

The rate of reaction is the speed of a reaction. This shows that my data is quite accurate. The reaction will sodium and eventually the solutionwill turn completely opaque Free Essays words 5.

When the solution is made more concentrated, there are a greater number of molecules in the same space. This good because it shows that for every increase in concentration is a decrease in rate of reaction. The bars of 1M and 2M overlap and this shows that there is no real difference. There are a few mild outliers.

We must produce a piece of coursework investigating the rates of reaction, and the effect different changes have on them. How about make it original? Aim My aim is to investigate how changing the concentration of reactants can change the rate of reaction between hydrochloric acid and sodium thiosulphate.
