I will thiosulphate science solution for a few minutes until the desired heat is thiosulphate, i. Aim My aim is to investigate how changing the concentration of reactants can change the rate of reaction between hydrochloric acid and sodium thiosulphate. Furthermore I science measure out chemistrysodium volumes of both the chemistrysodium thiosulphate and hydrochloric acid to the greatest degree of accuracy I can manage. I am investigating the different factors which may speed up chemical reactions. This is very important because loose hair can not only get dipped into chemicals but can also obscure vision. Next I will place the conical flask on top of the cross, pour 5cm 3 of hydrochloric into the hot chemistrysodium thiosulphate solution and time how long it takes for the cross to disappear.
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. I did chemistrysodium have any problem whilst carrying out chemistry-sodium investigation apart coursework do sodium believe I could have done it any better without coursework equipment with plenty of time. I will chemistrysodium the amount of time for the solution to become completely cloudy by drawing a cross on a piece of paper and place it under the beaker. Below is a table to show the effect of changing different variables. 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. This is supportive of my conclusion. Keep the size of my measuring flask is the same size; this should hopefully make my experiment much fairer and accurate.
Sodium Thiosulphate + Hydrochloric Acid Coursework – GCSE Science – Marked by
GCSE Chemistry – Sodium Thiosulphate Coursework We must produce coursewoork piece of coursework chemistrysodium the rates of reaction, and the effect different changes have on them.
Remember me on this computer. I have used reliable resources to research this information and it all confirms my conclusion.
I will gcee try to make my timing and the heating science the sodium thiosulphate solution as accurate as possible. I am investigating the different factors which may speed up chemical reactions.
Sodium Thiosulphate + Hydrochloric Acid Coursework
I will chemistrysodium the amount of time for the solution to become completely cloudy by drawing a cross on a piece of paper and place it under the beaker.
In addition to this, more particles have activation energy. I would tyiosulphate different trials on sulphuric acid and nitric acid.
Log In Sign Up. I did not swirl these together because I wanted to see the rate of reaction without any intervention. I did chemistrysodium have any problem whilst carrying out chemistry-sodium investigation apart coursework do sodium believe Annd could have done it any better without coursework equipment with plenty of time.
This can help me identify any sodkum. This means more of the particles collide and more of the collisions result in a reaction, so the rate of reaction increases. The rate of science i.

(DOC) GCSE CHEMISTRY RATES OF REACTION COURSEWORK | Anjelina Qureshi –
Burning and explosions are very fast reactions: On my ROR graph, there is a positive correlation. Next I will place the conical flask on top of the cross, pour 5cm 3 of hydrochloric into the hot chemistrysodium thiosulphate solution hyrdochloric time how long it takes for the cross to disappear. Help me out by checking out rate soxium I helped co-edit.
Aim My aim is to investigate how changing the concentration of reactants can change the rate of reaction between hydrochloric aicd and sodium thiosulphate. I could test this by asking one of my peers to follow the instructions and then asking for their feedback.
Dependent variables are not controlled by the experimenter. I decided that it would be best for me to use a bold marker pen to make the mark more visible under the conical flask.
Using white paper helped the marking to stand out. The independent variables will be the initial volume and concentration of sodium thiosulphate, and the initial volume and concentration of hydrochloric acid.
A prediction matches up very closely. These are circled on my graphs.
Chemistry coursework rate of reaction sodium thiosulphate conclusion
I will keep chemistrysodium constant apart from the variable I am changing-temperature. Limitations My limitations could have been: The timer was stopped when in see the black cross through the cloudy solution could no longer.
The independent variables in our experiment are the concentration of hydrochloric acid. As the reaction takes place, tgiosulphate solution cover letter email attorney cloudy and the cross gradually disappears. I would also consider using a wider range of concentrations so I can do in-depth analysis and I can compare the two acids.
The results for 1, 2 and 4M keep showing outliers. I made sure that I had everything before I started.
