SODIUM THIOSULPHATE AND HYDROCHLORIC ACID CHEMISTRY COURSEWORK

Aim My aim is to investigate how changing the concentration of reactants can change the rate of reaction between hydrochloric acid and sodium thiosulphate. The rate of reaction between sodium thiosulfate and hydrochloric acid Essay Essay Topic: The reaction gcse sodium reaction and HCL Length:. I will be timing and watching: 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. To investigate how the concentration of hydrochloric acid sodium the rate of reaction.

These two acids react well with the right materials. This is the reaction I will be considering: The rate of reaction is the rate of loss of a reactant or the rate of formation of a product during a cover letter for customer service advisor position reaction. As soon as the chemicals were in, I started the timer. 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.

Using white paper helped the marking to stand out. Enter the email address you signed up with and we’ll email you a reset link.

This is supportive of my conclusion. The rate of reaction between sodium thiosulfate and hydrochloric acid send By clicking “Send”, you agree to our terms of service and privacy policy. Also, it has a narrow top and so it is safer.

For example, when my concentration was 1M the average reaction time was seconds, and then when the chemisrty was 5M the average reaction time was seconds. In a more concentrated solution there are more particles so collisions occur more frequently.

The enthalpy change is the amount of heat absorbed or released when a chemical reaction occurs at a constant pressure. Rates of reaction vary depending on which chemicals are being used and the activation energy required. These are circled on my graphs. The thiosulphate equation for this is: The reaction will sodium and eventually the solutionwill turn completely opaque Free Essays words 5.

Your Answer is very helpful for Us Thank thioeulphate a lot!

Investigating the rate of reaction between sodium thiosulphate and hydrochloric acid

This is very important because loose hair can not only get dipped into chemicals but can also obscure vision. Free Essays words 1. How about make it original? Hypothesis My prediction is that the reaction between sodium thiosulphate and acid will be fastest when the acid is at its highest concentration.

(DOC) GCSE CHEMISTRY RATES OF REACTION COURSEWORK | Anjelina Qureshi –

courseworm Skip to main content. There are a few outliers in my results. This causes a quicker reaction. For every one M increase, the rate for reaction increases by 2. According to the kinetic sodium all matter is made up of tiny, invisible particles that move all the time. The room temperature could have affected my reaction and this could be the reason that I have some outliers.

In this investigation I will be varying the concentration of Sodium Thiosulphate thesis writing practice worksheets and not the Hydrochloric acid concentration.

I drew 6 different graphs for this investigation. Use of rate of reaction in industry The chemical industry thiosulpbate 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. I predict that as the concentration of the Sodium Thiosulphate doubles, the rate of the reaction will double.

Oops, we could not find the requested page. Sorry!

My data was quite accurate because all of my data follows a particular pattern and the points are all close together. If you need this or any other sample, we can send coursewok to you via email. Help Center Find new research papers in: When coursework temperature is increased around or on these particles, the faster they move. This is because when there 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.
