I could have use a colorimeter to identify colour changes in the products. 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. Sodium thiosulphate is a colourless, crystal like compound and is used for dyes and is also a salt. I think this because there is outliers in the 2M set of data and the error bars overlap between 1M and 2M on my error bar graph. 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:

The higher the temperature of the sodium thiosulphate the faster the Essay – The higher the temperature coursework the sodium thiosulphate the faster creative writing online courses australia reaction of the two liquids. The reaction that occurs produces sulphur dioxide, water and sodium chloride Free Essays words 4. I have used reliable resources to research this information and it all confirms my conclusion. Building Book Love For example. Papers] Free Essays words 1. Die gesuchte Seite konnte nicht gefunden werden oder ein Fehler ist aufgetreten. I stood up to allow more space for others to walk by between the rooms.

reaction between sodium thiosulphate and hydrochloric acid coursework

The timer hyrrochloric stopped when in see the black cross through the cloudy solution could no longer. Dependent variables are not controlled by the experimenter. Improvements I could have used greater or a more systematic range of temperatures. For example, rusting is a slow reaction; it has a low rate of reaction. The bars for 3M, 4m and 5M do not overlap.

On my ROR graph, there is a positive correlation. I would do different trials on sulphuric acid and nitric acid. The rate of reaction is hyrdochloric speed of a reaction.



This good because it shows that for every increase in concentration is a decrease in rate of reaction. I would also consider using a wider range of concentrations so I cousrework do in-depth analysis and I can compare the two acids. This can be done by: The enthalpy change is the amount of heat absorbed or released when a reatcion reaction occurs at a constant pressure. Aim My aim is to investigate how changing the concentration of reactants can change the rate of reaction between hydrochloric acid and sodium thiosulphate.

reaction between sodium thiosulphate and hydrochloric acid coursework

Building Book Love For example. Enter the reacfion address you signed up with and we’ll email you a reset link. This increases the likelihood of reactants colliding properly and so increases the rate of the chemical reaction.

This is the reaction I will be considering: The conical flask and all other equipment must be clean as any impurities may contaminate my experiment.

This can help me identify any faults.

My data was precise because most of the points on my graphs are close to the line and are all close by each other. If you need this or any other sample, we can send it to you via email. Log In Sign Up.

The reaction between Sodium Thiosulphate and Hydrochloric Acid.

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.


These two acids react well with the right materials.

It can also be found in the stomach. In this investigation I will use the following word equation: I predict that as the Sodium Coursework sodium increases the rate of reaction will also increase Research Papers words 3. This could have happened because of calculation errors, human errors, recording errors or a fault with the equipment that we used. Sorry, but copying text is forbidden on this website! This is because when reactuon are more molecules in the solution, there are more molecules to collide so this will speed up the reaction, and therefore it is more likely they will collide with each other.

Also, it has a narrow top and so it is safer.

The rate of reaction between sodium thiosulfate and hydrochloric acid Essay

I had to make sure that my classmates were safe as well as myself. The rate of reaction between sodium thiosulfate and hydrochloric acid. Sorry, but copying text is forbidden on this website.

This is supportive of my conclusion. I have highlighted the 2M results on my tables because it seems as though there is a problem xodium that set.
