The graph shows that my prediction was correct, which was that as the concentration of Sodium Thiosulphate decreases the rate of reaction increases. My results were outstanding seen as though I had no outliers or the error bars on my graph are very small.
The effect of concentration on the rate of reaction of Magnesium with Sulphuric Acid. From Wikibooks, open books for an open world The more molecules in a chemical the more concentrated it is.
Investigating the rate of a reaction.
I plan to use hydrochloric acid and sodium hydroxide. Your teacher will have a good idea what to expect and you must be able to justify all your write-up.

Uses and environmental effects of — dichloromethane, trichloromethane, tetrachloromethane, iodoform, freons, DDT.
In other words give some detailed ideas on further work that would provide additional relevant evidence. Preparation of soybean milk and its comparison with the natural milk with respect to curd formation, effect of temperature, etc.
Some of the work done here in presenting the results, e. No advanced equipment is needed and accurate results can be gained without difficulty. This deals with the time taken for concentration of sodium thiosulphate and react it with hydrochloric acid and see Rate Of Reaction Concentration Coursework — cs.
Subscribe to this RSS feed. I ensured that the equipment, mainly the beaker was cleaned after an experiment. You expressly agree that any use of the Material is entirely at your own risk.
This is an effective about the best of sodium shoot. On the other hand, some students cry out when they prepare for their exam. However, they will cool a little standing out in the laboratory, so not completely satisfactory solution to the problem.
In addition models and exhibits for Chemistry coursework sodium thiosulphate concentration ,depicting basic principles and application in daily life may also be included.
For example when there was 12ml of STS the average time was seconds. I could have also changed the concentration of the HCL solution. In your 'method' description use the correct units or descriptors. To find the effect of concentration of thiosulphate on the rate of reaction between sodium thiosulphate and hydrochloric acid.
It is measured by dividing 1 by the time taken for the reaction to take place. You must give details of how long you might time the experiment as well as the time interval between experimental readings REMEMBER you can change your 'recipe' or way of doing the experiment.
A solid that is present in a solution can only react when particles collide with the surface of the solid. The theory behind this experiment is that 'Increasing the concentration can increase the rate of the reaction by increasing the rate of molecular collisions.
My smooth line on my graph of results clearly shows that concentration of a substance does have an effect on the rate of reaction. Not only is the results reliable but they are easy to understand as for the key which describes the part on the graph such as line of best fit, error bars etc.
I also think my results were accurate. The results are initially processed into graphical form 'graphing' for several reasons for both the analysis and evaluating the experimental Do your results seem consistent and accurate? Making and recording of appropriate observations during chemical reactions including: You expressly agree that the Company is not liable or responsible for any defamatory, offensive, or illegal conduct of other subscribers or third parties.
Enzyme catalysed reactions e. To find out how the concentrations of the reactants affect the rate of reaction. Measuring Rates of Reaction Science Revision: This again shows that my test was a fair test.
Sodium-thiosulphate — used as solution as part of my experiment Hydrochloric Acid — used as solution as part of my experiment Beaker — used for carrying the solution Measuring cylinder — used for measuring the volume of solution Timer — used to measure the time taken for the solution to get cloudy Calculator — used to calculate the average time Conical Flask — used to carry out the experiment Black-cross card- used to see weather or not the solution had turned fully cloudy.
Fed reaction between different hydrochloric acid and security failure solution GCSE Coherence Coursework Investigating the rate of a missile.
One of my problems I encountered during my experiment was the time taken to press the timer which in my opinion affected my results. My experiment was carried out very safely.Concentration and rates of reaction - "Disappearing cross" experiment Aim I am ideal female body structur investigating the effect of the.
Extracts from this document chemistry coursework sodium thiosulphate Introduction.
KCSE revision tips. GCSE chemistry. · This qualities of a hero essay page reapplicant essay is an Shy. Chemistry Coursework - How the concentration effects the rate of reaction between sodium thiosulphate Using the collision theory I have come to the conclusion that for a reaction to take place two reactant particles must collide with sufficient energy.
The other redox titration involves iodine oxidising sodium thiosulphate. Starch is the indicator for titrations involving iodine, since iodine and thiosulphate produce a dark blue-black compound. The techniques mentioned under acid-alkali titrations apply to redox titrations.
But to make sure, did we have to change concentration of the sodium thiosulphate or hydrochloric acid? Because, technically everyone in my class were changing the first one, when on this site: Need coursework for rate of reaction between sodium thiosulfate and hydrochloric a Ib chem help me pls Chemistry Course Work - Rate of Reaction.
Practical Chemistry for CSEC is a unique practice book for CSEC. It provides a wealth of revision exercises, and a guide to all the detailed experimental work covered in the CSEC Chemistry syllabuses.
