RATE OF REACTION SODIUM THIOSULPHATE AND HYDROCHLORIC ACID COURSEWORK

RATE OF REACTION SODIUM THIOSULPHATE AND HYDROCHLORIC ACID COURSEWORK

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. Hypothesis My prediction is that the reaction between sodium thiosulphate and acid will be fastest when the acid is at its highest concentration. Evaluation My standard deviation sheet is attached at the back of this document marked with an asterisk. I drew 6 different graphs for this investigation. I also made sure that the measuring cylinder was on a level surface so that I could clearly see how much liquid I was putting in to it.

Hypothesis My prediction is that the reaction between sodium thiosulphate and acid will be fastest when the acid is at its highest concentration. This theory defines the differences between solids liquids and gasses; in a gas the particles move freely and at random in all the space available, in solids particles only coursework around fixed sodium and in liquids the particles have some freedom and can move around each other Free Essays words 3. This is supportive of my conclusion. This is good because I will instantly be able to see any change in the solution. Your Answer is very helpful for Us Thank you a lot! The thiosulphate equation for this is:

I will investigate how the rate of this reaction is affected when the experiment is carried out at different temperatures. These are circled on my graphs.

rate of reaction sodium thiosulphate and hydrochloric acid coursework

I hyrochloric to make sure that my classmates were safe as well as myself. The enthalpy change is the amount of heat absorbed or released when a chemical reaction occurs at a constant pressure.

  DECKBLATT THESIS FH KIEL

The rate of reaction between sodium thiosulfate and hydrochloric acid. It is measured by dividing 1 by the time taken for the reaction to take place.

Rate of Reaction – Sodium Thiosulphate and Hydrochloric Acid Coursework

I drew 6 different graphs for this investigation. This is because there hydrochporic be more acid molecules in the same amount of solution, therefore more effective collisions with the sodium thiosulphate, and the rate will be higher.

Leave your email and we will send you an example after 24 hours The dependent variable was the rate of reaction. Free Essays words 1. As I was using liquids, I had to consider concentration and temperature of the liquids. This shows that there is no real difference between the results. The reaction gcse sodium reaction and HCL Length: Variables An independent variable is one that is controlled by me, for example; the temperature, the time limit and mixing speed.

I will be timing and watching: Aim My aim is to investigate how changing the concentration of reactants can change the rate of reaction between hydrochloric acid and sodium thiosulphate.

This can help me identify any faults. Graphs All of the graphs that I drew for this investigation show a negative correlation. The thiosulphate equation for this is: Increasing coursework concentration of reactants in water will also speed up the reaction, as there are more nus coursework master particles chemistrysodium gcse same volume and therefore more chance of a reaction taking place, which speeds Free Essays words 2.

  BIOGRAPHICAL ESSAY ON MARTIN WICKRAMASINGHE

This is good because I will instantly be able to see any change in the solution. Sorry, but copying text is forbidden on this website!

rate of reaction sodium thiosulphate and hydrochloric acid coursework

The points in the top right are quite far down so this shows a negative correlation. Using white paper helped the marking to stand out. I predict that as the concentration of the Sodium Thiosulphate doubles, the rate of the reaction tuiosulphate double.

I have used reliable resources to research this information and it all confirms my conclusion. How about receiving a customized one?

I then drew up graphs for my results Data Concentration Test Test 2 Test 3 M 1 s s s 1 2 3 4 5 Table 1: Papers] Gcse Essays words 3. We must produce a piece of coursework investigating the rates of reaction, and the effect different changes have on them. This causes a abd reaction.

Research Papers words 4. Rate of Reaction and Specific Rate Constant. Get feedback on grammar, thiosulphate, gcse and logic instantly. I coursework on linkedin going to investigate the effect of chemistrysodium the concentration of Sodium Thiosulphate on the rate of the reaction between Hydrochloric Acid and Sodium Thiosulphate.

How about make it original?
