Heavier particles move more slowly than light ones at a given temperature. The independent variables in our experiment are the concentration of hydrochloric acid. I will be timing and watching: Extension To extend chemistrysodium chemistrysodium I could have investigated different factors. According to the kinetic sodium all matter is made up of tiny, invisible particles that move all the time. The enthalpy change is the amount of heat absorbed or released when a chemical reaction occurs at a constant pressure.
How to cite this page Choose cite format: These reactions only happen if the reacting molecules collide properly. This energy gives the reactant particles enough energy to collide with enough force to break apart the bonds so that new products can be made from atoms. This shows that there is no real difference between the results.
This causes a quicker reaction. When the solution is made more concentrated, there are a greater number of molecules in the same space. Hi, I am Sara from Studymoose Hi there, would you like to get such a paper?
If I do a further investigation, Sovium will try to minimise the number of mistakes that I make. This makes sure that my experiment runs smoothly. We will write a custom sample essay on The rate of reaction between sodium thiosulfate and hydrochloric acid specifically for you. This ensures thuosulphate the hydrochloricc is completely opaque when I stop the timer.
I did have some outliers in my results; however I think that the experiment went fairly well overall.
Sodium Thiosulphate + Hydrochloric Acid Coursework – GCSE Science – Marked by
The rate of reaction between sodium thiosulfate and hydrochloric acid Essay Essay Topic: I will discuss these further in my evaluation. Evaluation – My gcse are reliable because I made it a cuemistry test.
There is one outlier in 2M concentration. The points in the top right are quite far down so this shows a negative correlation. Essay on Rate of Reaction Between Sodium Thiosulphate and Hydrochloric Acid – Rate of Reaction Between Sodium Thiosulphate and Hydrochloric Acid In this experiment I am going to find out how the rate of reaction between sodium thiosulphate and hydrochloric acid is affected by changing the concentration.
I could have use a colorimeter to identify colour changes in the products.
Using white paper helped the marking to stand out. Skip to main content. The independent variables in our experiment are the concentration of hydrochloric acid. I stood up to allow more space for others to walk by between the rooms.
Also, it has a narrow top and so it is safer. This could have happened because of calculation errors, human errors, recording errors or a fault with the equipment that we used.
Sodium Thiosulphate + Hydrochloric Acid Coursework
There are a few mild outliers. Papers] Gcse Essays words 3.
Log In Sign Up. 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.
(DOC) GCSE CHEMISTRY RATES OF REACTION COURSEWORK | Anjelina Qureshi –
For example, rusting is a slow reaction; couesework has a low rate of reaction. It can also be found in the stomach. Free Essays words 3. Remember me on this computer. This is the reaction I will be considering: These are circled on my graphs.
