Sodium Thiosulphate And Hydrochloric Acid Coursework Analysis

In this coursework, i will include background knowledge, prediction, safety, results, calculations, graphs, an analysis, conclusion and an evaluation. August 18, 2018) how write the analysis for a reaction between sodiumthiosulphate and hydrochloric acid gcse science coursework (chemistry) planning skill area p write down the aim of your investigation. To do this we added water to the acid and did the experiment again 4 times, decreasing the concentration of the acid by 5cm3 each time.

Then we drew a cross onto a piece of paper and put an empty conical flask on top of the paper. This can cause reactions in the beakers and will lead to inaccuracies. Also to ensure a fair test i will use the same beakers and measuring cylinders each time for holding the thio and the acid.

In this investigation i will use the following word equation sodium thiosulphate hydrochloric acid in this investigation i will use the following symbol equation how does the concentration of the sodium thiosulfate affect the rate of reaction to hydrochloric acid? Investigationhow does the concentration of the sodium thiosulfate affect the rate of reaction to hydrochloric acid?contents page 1 contents, aim, prediction, equation, diagrampage 2 equipment, preliminary experimentspage 3 page 4 page 5 page 6 page 7 page 8 aim in my investigation i am trying to find out how the rate of reaction between sodium thiosulfate and hydrochloric acid gets affected but the concentration of the thiosulfate. First of all we measured out 25cm3 acid and 25cm3 sodium thiosulphate. My results clearly show that as the concentration decreases, the time increases in the experiment.

Finally, we will make sure that the same person judges when the cross is no longer visible or the reaction times result could not be accurate, as 2 people could have different eyesight and therefore different opinions on when the x has disappeared. The reaction that will be taking place will follow the rate at which sulphur is formed in the reaction of sodium thiosulphate with dilute hydrochloric acid. I will look at the various factors affecting the reaction and select one variable to change, while the rate of reaction between hydrochloric acid and calcium carbonatecalcium carbonate reacts with hydrochloric acid to form carbon dioxidegas.

The factors that affect the rate of reaction are use of a catalyst i have done a preliminary experiment to help me decide the range of concentrations to use and how much of a difference in concentration to leave between each one. These are just a few of the chemical properties of nitric oxide. If the reactants take a relatively short time to form the products, the reaction is known as a fast one.

It is used in photocells because of the electrical conductivity of thallium sulphide. Next, we poured the 25cm3 acid and 25cm3 thio into the conical flask and started the stop clock. I am going to investigate how the concentration of the acid effects the speed of the reaction. My preliminary results also show that 5cm3 is a low enough concentration to begin with. To investigate the effects of change in concentration on the rate of reaction between sodium thiosulphate and hydrochloric acid.

. The reaction that will be taking place will follow the rate at which sulphur is formed in the reaction of sodium thiosulphate with dilute hydrochloric acid. To keep this a fair test i have made sure that the acid used is the same amount every time.

Thallium was originally used to help treat ringworm and many other skin infections. In this investigation i will be varying the concentration of sodium thiosulphate only and not the hydrochloric acid concentration. In this investigation i will use the following word equation sodium thiosulphate hydrochloric acid in this investigation i will use the following symbol equation how does the concentration of the sodium thiosulfate affect the rate of reaction to hydrochloric acid? Investigationhow does the concentration of the sodium thiosulfate affect the rate of reaction to hydrochloric acid?contents page 1 contents, aim, prediction, equation, diagrampage 2 equipment, preliminary experimentspage 3 page 4 page 5 page 6 page 7 page 8 aim in my investigation i am trying to find out how the rate of reaction between sodium thiosulfate and hydrochloric acid gets affected but the concentration of the thiosulfate.

Also the size of the cross on the piece of paper is the same. We then added the contents of the cylinder to the conical flask along with the 25cm3 sodium thiosulphate. This can cause reactions in the beakers and will lead to inaccuracies.

Then we drew a cross onto a piece of paper and put an empty conical flask on top of the paper. In this piece of coursework, i will study how concentration affects the rate of reaction. If the reactants take a relatively short time to form the products, the reaction is known as a fast one.

Cacl h o cocalcium carbonate hydrochloric acid calcium chloride water carbon dioxideequipment---------delivery tubeconical flaskhydrochloric rate of reaction of dilute hydrochloric acid and sodium thiosulphate to investigate the change in rate of reaction between dilute hydrochloric acid and sodium thiosulphate as the concentration varies. The temperature is also the same because the results could be anomalous if tested in different conditions. My experiment is time based and i will not have enough time to go lower.

I am going to investigate how the concentration of the acid effects the speed of the reaction. This is because if i put the thio into a beaker that had previously held acid then it could start off a reaction and affect the overall reaction rate. To do this we added water to the acid and did the experiment again 4 times, decreasing the concentration of the acid by 5cm3 each time. In the experiment the sulphur will appear as an extremely fine precipitate. My observations in table-1 led me to believe that the ammonia (nh3) was lighter.
