Sodium Thiosulphate coursework.

#

We must also chemistry coursework sodium thiosulphate conclusion sure that we add both the water and the Sodium Bad leadership essay at exactly the same time into the beaker with the hydrochloric acid in itor it could affect the results of the experiment. Which consisted of many types or variables such as:

#

Rate of Reaction - Sodium Thiosulphate and Hydrochloric Acid

#

I also had to choose which type concentration I needed either 1 molar or 2 molars concentration types. The graph above is the average time taken for the solution to become cloudy.

#

A grade GCSE chemistry coursework - Rates of reaction Decomposition of sodium thiosulphate

#

This would have brought more evidence to support the idea that the higher concentration of a substance, the faster it will react.

#

Chemistry Coursework

#

I predict that as concentration is doubled the amount of time taken for the reaction is halved. I am very confident with the method I used whilst using simple equipment and obtaining fantastic results and my experiment was a success.

#

Chemistry Gcse Coursework Rates of Reaction

#

Overall, however, we followed the stated method for each of the experiments and I believe that it went quite well and it gave a good set of results that display the predicted pattern for this experiment. Chemistry coursework sodium thiosulphate conclusion had to add the Sodium Thiosulphate and the water at the same time for this to be a fair test also.

#

#

Similarly my real experiment was done very precisely such as calculating or measuring the results or measuring the amount of solution in each beaker etc. I will also be careful when heating up the solutions and will sodimu all times wear safety goggles and also remain standing throughout the experiment.

#

#

This is not half the time; it had an error margin of 1.

#

#

Piece of paper with cross on it To determine cloudiness of liquid.

#

#

We repeated this many times, adding different amounts of Sodium Thiosulphate and water each time, and recording the time taken each time.

#

#

The results could have been improved by repeating thiosulpate investigation more times so that I can further improve the reliability of my data. The initial volume of water.

#

#

In a more concentrated solution there are more particles so collisions occur more frequently Below is a table to thiosulphatee the effect of changing different variables.

#

#

As the concentration of Sodium Thiosulphate decreases so the length of time the reaction takes to be completed increases.

#

#

To ensure our safety goggles and aprons are always worn to protect the eyes and body. It would also be preferable to wear a scientific apron, however this is coursewor essential.

#

#

If solutions of reacting particles are made more concentrated there are more particles per unit volume.

#

#

We repeated this many times, adding different amounts of Sodium Thiosulphate and water each time, and recording the time taken each time. We must make sure that coats and bags are all out of the way while doing the experiment.

#

#

I am very confident with the method I used whilst using simple equipment dodium obtaining fantastic results and my experiment was a success. I made sure that I was wearing my safety goggles whilst I carried out my test.

#

#

On each experiment I will take three readings and work out an average from the data I have obtained. I recorded my results using a timer just to see if the experiment worked.

#

#

Also when the lower boiler thesis were used it was detected that thiosulphaate cross disappears in some areas of the flask but is still visible in a corner or in a little area. This problem would have been avoided if I used more accurate equipment.

#

#

In order to provide additional evidence and extend my investigation to find out more and chemistyr up my conclusion I could perhaps repeat the experiment using specialist equipment. Sodium Thiosulphate and Hydrochloric Acid Reaction Investigation Essay - Sodium Thiosulphate and Hydrochloric Acid Reaction Investigation Aim To see the effects of concentration on the rate of a reaction between sodium thiosulphate chemistry coursework sodium thiosulphate conclusion hydrochloric acid.

#

We then waited for the black cross to be completely obscured by the mixture.

#

So chemistry coursework sodium thiosulphate conclusion the sodim particles increased which meant that there where more particles colliding with the hydrochloric acid particles. This really helped me with my chemistry coursework and I used the physics one for my physics a coursework and I got an An overall thank you so much!!!!

#

I can also improve my experiment by using a turbidity sensor which judges how cloudy things are. Thank you so much!!!!

#

In a more concentrated solution there are more particles so collisions occur more frequently

#

Also many other variables affect the collision rate to increase such as Catalysts and temperature etc.

Reaction Between Hydrochloric Sofium and Sodium Thiosulphate Essay - Reaction Between Hydrochloric Acid and Sodium Thiosulphate Introduction I will be conducting two experiments to determine how two factors affect the rate of reaction in the reaction between hydrochloric acid and sodium thiosulphate.

To make sure that my test went accurately and precisely I made sure that my timing was accurately done not pressing the timer too early or late. This problem would have been avoided if I used more accurate equipment. My results do support the first part of my prediction. I could have also changed the concentration of the HCL solution. It is obvious that there is a general trend in the results. This is the required energy for the reaction to get started.

Also many other variables affect the collision rate to increase such as Catalysts and temperature etc. Although there are a number of ways in which we could have made the results more reliable.

If you did not, then you would need to write about it in your conclusion. Lani - this experiment was done 3 years ago. Great article which really helped me with my experiment. The size of this activation energy is different for different reactions. We could have, however, used Sodium Thiosulphate as a constant, but we had chosen to use Hydrochloric acid. I predict that if we continued increasing the concentration of thiosulphate a point will be reached when the rate of reaction will not increase any further but will stay constant.

This makes it easier to evaluate the results and come to a conclusion. Books, Literature, and Writing. Only a small percent result in a reaction. Consequently the rate of collision increases.
