SODIUM THIOSULPHATE AND HYDROCHLORIC ACID COURSEWORK EVALUATION

This is good because I will instantly be able to see any change in the solution. How the rate of reaction changes in a reaction between Hydrochloric Acid and Sodium Thiosulphate words – 4 pages Chemistry coursework: This causes a quicker reaction. I will collect this gas in a gas syringe and will time how long it takes for the reaction to produce cm3 of carbon. I did have some outliers in my results; however I think that the experiment went fairly well overall. However, they will gcse a little standing out in chemistrysodium laboratory, so not completely satisfactory solution to the problem.

Explain why best data at the start? The room temperature could have affected my reaction and this could be the reason that I have some outliers. It is often used as a chemical intermediate and in petroleum production, food processing, pickling, and metal cleaning. On the advanced gas calculations pagechemistry-sodium sources of error and their correction are discussed in calculation example Q4b. An input of heat energy is required to start some reactions.

Chemistry-Sodium Thiosulphate

I could have use a colorimeter to identify colour changes in the products. Measuring rate … … Pressure effect … Rate of reaction … Reaction profiles I would do different trials on sulphuric acid and nitric acid. I tied my hair back, tucked in my tie and pushed all stools and bags under the desk where there is no risk of anyone tripping.

In the experiment the sulphur will appear as an extremely fine precipitate. Investigating the rate of reaction between Hydrkchloric Thiosulphate and Hydrochloric Acid words – 7 pages predicted, the more concentrated solutions reacted more quickly than the weaker ones.

Investigation Of Sodium Thiosulphate And Hydrochloric Acid

The reaction that will be taking place will follow the rate at which sulphur is hydrochloricc in the reaction of sodium thiosulphate with dilute hydrochloric acid. In my scatter graph with line of best fit, most of the points are close to the line. Log In Sign Up.

  EPEKTO NG PAGLALARO NG ONLINE GAMES THESIS

The purpose of this investigation is to record the amount of time taken for a reaction to occur when sodium thiosulphate is mixed with hydrochloric acid. Log In Sign Up. These two acids react well with the right materials.

sodium thiosulphate and hydrochloric acid coursework evaluation

The effects of change in concentration on the rate of reaction between Sodium Thiosulphate and Hydrochloric Acid words – 7 pages cm3 of water will be added to complete the solution. I drew 6 different graphs for this investigation.

An investigation to see how Hydrochloric acid reacts with Magnesium to produce Hydrogen gas words – 8 pages The aim of the investigation is to see how different concentrations of Hydrochloric acid affect the rate at which hydrogen gas is produced when it is reacted with a strip of magnesium.

sodium thiosulphate and hydrochloric acid coursework evaluation

The flask is viewed from evaluahion top and then as the cross disappears the. The main reason they did not think of them before the ‘s was because scientists did not know about stimulated emission.

Gcse Coursework Chemistrysodium Thiosulphate – Sodium Thiosulphate + Hydrochloric Acid Coursework

Limitations My limitations could have been: Also in order to make it a fair test I am going to keep the following variables the same: In this investigation I will use the following word equation: I decided that it would be best for me to use a bold marker pen to make the mark more visible under the conical flask.

Racism in the Criminal Justice System. As soon as the chemicals were in, I started the timer. Also, it has a narrow top and so it is safer.

(DOC) Sodium Thiosulphate in Hydrochloric Acid | Antonio Motta-Marques –

On my ROR graph, there is a positive correlation. As an inert and stable liquid, water was used to alter concentration of Sodium Thiosulphate without changing the end amount of solution. The effects of change in concentration on the rate of reaction between Sodium Thiosulphate and Hydrochloric Acid words – 7 pages cm3 of water will be added to complete the solution.

The experiment shall be carried out twice, to give accuracy, and allowing me to check for agreement between results. Chemistry-Sodium Thiosulphate Found what you’re looking for? VariablesI changed the concentration of the hydrochloric acid by adding water to it.

What further experiments, thiosulphate the same method or another method, could be done to support your prediction or conclusion? The results for 1, 2 and 4M keep showing outliers. In the case of liquid solutions, the concentration of the elements is also important when considering whether the reaction will be successful or not. Using white paper helped the marking to stand out.

Analysing and considering the evidence – what reaction the results mean in terms of your prediction and theory!
