SODIUM THIOSULPHATE COURSEWORK

One of the best methods to work out the rate equation is to find out the concentration of the solutions after at different time intervals. Disappearing X ExperimentIntroductionI am going to investigate the rate of reaction between sodium thiosulphate thio and hydrochloric acid. PLAN A chemical reaction takes place over a specific period of time i. Firstly, we need to keep a chemical at a constant concentration. The rate of reaction is the speed at which a chemical reaction takes place. The rate graph has three curves which differentiates the three orders the following three graphs show the three curves.

Investigating the Rate of Reaction of Sodium Thiosulphate and Hydrochloric Acid – Investigating the Rate of Reaction of Sodium Thiosulphate and Hydrochloric Acid I predict that the higher the concentration then the faster the reaction, this is because when water is added the sodium thiosulphate solution and the hydrochloric acid have a more neutral pH and it becomes more dilute then it will be less reactive will the other particles in the solution. Also The person timing the experiment will look for the disappearance of the cross, otherwise there would be a time lapse between seeing the cross disappear and telling the other person to stop the clock and then eventually stopping the clock. The earliest know plants that occurred were the ferns, and they appeared about million years ago Plant, These are surface area, temperature, concentration and catalysts I am going to investigate how varying the concentration of Sodium Thiosulphate affects the rate of reaction with Hydrochloric Acid.

This can be explained using the collision theory. An investigation of the affect of the concentration an of the rate of reaction. VariablesI changed the concentration of the hydrochloric acid by adding water to it. However I am restricted by time and the available facilities which means I cannot repeat it.

I have come to this conclusion because of several reasons. Sodium Thiosulphate and Hydrochloric Acid Reaction Investigation Essay sodium thiosulphate coursework Sodium Thiosulphate and Hydrochloric Acid Reaction Investigation Aim To see the effects of concentration on the rate of a reaction between sodium sodium thiosulphate coursework and hydrochloric acid.

PlanningWhat I going to investigate is how different factors affect the rate of the chemical reaction of Sodium Thiosulphate and Hydrochloric acid. The higher the concentration of hydrochloric acid, the faster the rate of reaction. I am going to investigate the effect of changing the concentration of Sodium Thiosulphate on the rate of the reaction between Hydrochloric Acid and Sodium Thiosulphate.

To detect when cross disappears and sodium thiosulphate coursework clock at that sudden instance was very hard to judge effectively.

Rate of Reaction – Sodium Thiosulphate and Hydrochloric Acid Coursework

These are great study notes on the Punic Wars. To do this, I shall react We then added 50 cm3 of Sodium Thiosulphate to the hydrochloric sodium thiosulphate coursework, and at this time we do not need to add any water.

I predict that as concentration is doubled the amount of time taken for the reaction is halved. This is due to the energy barrier to overcome. Present to your audience Start remote presentation.

The concentration time graph looks something like the one on sodium thiosulphate coursework right. The experiment was done over a period of 5 days; I used the same cross I used for the first day however the light intensity was different on each sodium thiosulphate coursework. I will know when the reaction is taking place as the solution turns from clear to opaque.

Sodium Thiosulphate + Hydrochloric Acid Coursework – GCSE Science – Marked by

By taking these precautions it will keep the experiment accurate and keep sodium thiosulphate coursework to a minimum. This turns the solution sodium thiosulphate coursework. Comparison Of Two Horror movies: In the experiment the sulphur will appear as an extremely fine precipitate.

It is also important to keep the temperature the same to obtain fair results, however we do not have to worry about this as the temperature will be kept at room temperature through out the experiment. Investigating the Rate of Reaction of Sodium thiosulphate coursework Thiosulphate and Hydrochloric Acid – Investigating the Rate of Reaction of Sodium Thiosulphate and Hydrochloric Acid I predict that the higher the concentration then the faster the reaction, this is because when water is added the sodium thiosulphate solution and the hydrochloric acid have a more neutral pH and it becomes more dilute then it will sodium thiosulphate coursework less reactive will the other particles in the solution.

In this experiment we are trying to find the rate of reaction using concentration as a factor, so there is a number of things we need to make sure we do to keep it a fair test.

Immediately, we started the stopwatch.

My variable will be acid concentrationand I will keep every other aspect of my experiment the same. The collision theory will be involved in this, for instance the more sodium thiosulphate coursework the acid we use, the faster the reaction will occur and the We are trying to find out the affect of acid concentration on the rate of reaction, we are sodium thiosulphate coursework 2, 1.

History of the City of Hamilton. Reaction Rates Chemical Reactions Essays]. Delete comment or cancel. In a more concentrated solution there are more particles so collisions occur more frequently When the concentration was 50 Sodium thiosulphate coursework the average time was 0. Because there are more molecules about, the frequency of successful collisions is greater, and the reactions happen faster. Do you really want to delete sodium thiosulphate coursework prezi? It is a precipitation experiment.

The results I have produced are not entirely accurate as most of the measurements have been left up to human judgement. In which a precipitate is formed and causes the solution to become opaque.

Copy code to clipboard.

Put on your safety goggles and label the measuring cylinder. Only a small percent result in a reaction. Organizational Behavior – discuss motivational In the sodium thiosulphate coursework concentration there are more particles, so there is a higher chance of a reaction with the necessary amount of energy occurring.
