SODIUM THIOSULPHATE AND HYDROCHLORIC ACID COURSEWORK EVALUATION

Reactions that occur slowly have a low rate of reaction. I carried out my method with no problems at all, and received no anomalous results. There are 2 outliers Improvements and further investigations: In order to perform the experiment, the following Apparatus must be used: This was partly due to my own research and the collision theory which states that reactant paticles collide with one another to cause the substances to react. The simplest solution here, is to make sure all the chemicals have been standing in the laboratory prior to the lesson.

But in the early ‘s Albert Einstein was the first to describe this process. Evaluation My standard deviation sheet is attached at the back of this document marked with an asterisk. These chemicals are perfect for my investigation because they are both clear and colourless. In this coursework, I will include background knowledge, prediction, safety, results, calculations, graphs, an analysis, conclusion and an evaluation. Nobody in my group was asthmatic but if they were, I would have carried out the experiment near a window or in a fume cupboard. Racism in America Essay.

This shows that there is no real difference between the results.

I gained a good set of results and altogether I am pleased with the investigation. These two acids react well with the right materials. In this investigation I will be varying the concentration of Sodium Thiosulphate only and not the Hydrochloric acid concentration. This causes a quicker reaction.

Use of rate of reaction in industry The chemical industry makes medicine and many other substances such as; Limestone – this is used for building Sulphuric acid — used to make other substances Ammonia – used to make fertilisers.

Investigating the rate of reaction between Sodium Thiosulphate and Hydrochloric Acid words – 7 pages predicted, the more concentrated solutions reacted more quickly than the weaker ones.

Gives various statistics and figures about the canadian tourism industry, specifically on toronto, We need to be safe when doing this by amd goggles and making sure that we dispose of.

There are a few mild outliers. I drew 6 different graphs for this investigation.

Sodium thiosulphate and hydrochloric acid coursework conclusion

If I do a further investigation, I will try to minimise the number of mistakes that I make. See Rates of Chemistrysodium Notes.

sodium thiosulphate and hydrochloric acid coursework evaluation

Is there any other factor for the chemistry you are studying? Disappearing X ExperimentIntroductionI am going to investigate the rate of reaction between sodium thiosulphate thio and hydrochloric acid. Improvements and further investigations: This is because there will be more acid molecules in the same amount of solution, therefore more effective collisions with the sodium thiosulphate, and the rate will be higher. We done this using 0. AND on other associated web pages:.

My conclusion is justifiable because I have backed it up with points from my data and I have proved all the points that I made.

Investigation Of Sodium Thiosulphate And Hydrochloric Acid

Gcse system consists of a light beam courseowrk and sensor connected to computer and the reaction vessel is placed between the emitter and sensor. Reactions that happen quickly have a high rate of reaction. An investigation of the affect of the concentration an of the rate of reaction. In my scatter graph with line of best fit, most of the points courseeork close to the line. I would also consider using a wider range of concentrations so I can do in-depth analysis and I can compare the two acids.

  CASE STUDY AXEON N.V

We are trying to find out the affect of acid concentration on the rate of reaction, we are using 2, 1.

This website uses cookies to ensure you have the best experience. Enthalpy Enthalpy, in chemistry, is the heat content in a chemical reaction. 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. Does the ‘trend’ of all the graph lines support you’re your prediction, are all the results consistent with your coursework AND theory?

There were however minor issues that prevent this research from being fully accurate.
