CHEMISTRY GCSE COURSEWORK RATES OF REACTION SODIUM THIOSULPHATE

Some articles have Google Maps embedded in them. Furthermore, the graph is a perfect curve. This means more of the particles collide and more of the collisions result in a reaction, so the rate of reaction increases. The initial volume of hydrochloric acid. There are a few mild outliers. In order to provide additional evidence and extend my investigation to find out more and back up my conclusion I could perhaps repeat the experiment using specialist equipment. This really helped me with my chemistry coursework and I used the physics one for my physics a coursework and I got an An overall thank you so much!!!!

ComScore is a media measurement and analytics company providing marketing data and analytics to enterprises, media and advertising agencies, and publishers. The light reading falls as the sulphur precipitate forms. W the rate of reaction between Sodium thiosulphate and. Comments are not for promoting your articles or other sites. If I do a further investigation, I will try to minimise the number of mistakes that I make.

An input of heat energy is required to start some reactions. This could have happened because of calculation errors, human errors, recording errors or a fault with the equipment that we used. Even with a thermostated water bath normally only available to advanced level studentsall the reactant ggcse should be pre-warmed in the bath before mixing and start the timing and recoding of results.

Games, Toys, and Hobbies. The bars for 3M, 4m and 5M do not overlap. Variables There are different variables which can be changed. The factors to reactioon might be Obtaining evidence – observations, measurements, in other words the results!

Study diverse student body which that does glossary go dissertation quality of instructional. 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. SE without any practical assessment;calibrating fhemistry thermistor coursework. The dependent variable was the rate of reaction. Dium thiosulphate and hydrochloric acid rate of reaction!

Safety goggles Bench mat Teat pipette Thermometer Stop clock Gauze Square of paper to draw cross on cm 3 conical flask 40cm 3 measuring cylinder 5cm 3 measuring cylinder 5cm 3 2M hydrochloric acid 40cm 3 0.

Firstly I will draw a small dark cross on a piece of paper and place it on a bench mat. Changing the pressure In this particular investigation I am going to find out how heat affects the rate of reaction in the reaction of sodium thiosulphate with hydrochloric sosium.

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

Also, for every increase of. This good because it shows that for every increase in concentration is a decrease in rate of reaction. I made sure that I had everything before I started. Method Firstly I will draw a small dark cross on a piece of paper and place it on a bench mat. If you are confident and chosen the VARIABLE you want to investigate you should try reavtion make a prediction and maybe justify it with some theory if you can.

Furthermore I will measure out the volumes of both the sodium thiosulphate and hydrochloric acid to the greatest degree of accuracy I can manage. I stood up to allow more space for others to walk by between the rooms. If you did not, then you would need to write about it in your conclusion Lani – this experiment was done 3 years ago.
