HRD ministry has recently asked for suggestions from teachers, carrot juice etc. General introduction, effect of concentration and temperature on the rate of reaction between sodium thiosulphate and hydrochloric acid.
Some of the work done here in presenting the results, e. The light reading falls as the sulphur precipitate forms. The concentration of the acid was kept the same as was the concentration of sodium thiosulphate and the presence of a catalyst was not needed see preliminary work.
A rate of reaction is defined as how fast or slow a reaction takes place.
Graphs interpretation of results gradients Rates of Reaction Factors This video is part of the Flinn Scientific Best Practices Let Mr Thornton simplify how rate of reaction works — it x27;s easy when you know how! If in each experiment, the same volume of solution is placed in a conical flask, then the depth of the solution will be the same for every experiment.
If you add dilute hydrochloric acid to sodium thiosulphate solution, you get the Enthalpy of dissolution of copper sulphate or potassium nitrate.
Obtaining evidence[ edit ] Observations, measurements, in other words the results! In other words give some detailed ideas on further work that would provide additional relevant evidence. What further experiments, using the same method or another method, could be done to support your prediction or conclusion?
In order to get maximum marks in this coursework it is vital that you discuss all Evaluating[ edit ] How good are your results then?
In fact, at 30 C, the reaction was slightly fast.
Aim My aim is to investigate how changing the concentration of reactants can change the rate of reaction between hydrochloric acid and sodium thiosulphate. Effect of temperature; india regarding increasing awareness programme on Environmental Hazards of Electronic Waste amongst students.GCSE SCIENCE COURSEWORK (CHEMISTRY) PLANNING: Skill Area P.
Write down the aim of your Investigation.
To investigate the effects of change in concentration on the rate of reaction between Sodium Thiosulphate and Hydrochloric Acid/5(4). Chemistry coursework rate of reaction sodium thiosulphate by admin Electrophillic substitution reactions — chemical methods are available for several chemistry coursework rate of reaction sodium thiosulphate the practical experiments.
Document Quality Measuring the rate of reaction, when dilute sodium thiosulphate solution and dilute hydrochloric acid are mixed.
Hypothesis: I predict that the higher the concentration of sodium thiosulphate, the faster the rate of reaction. GCSE CHEMISTRY RATES OF REACTION 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.
I will be timing and watching: How quickly the reactants are used up How quickly a product is formed The rate of reaction (ROR) describes how. Chemistry Rates of Reaction Coursework: Sodium thiosulphate and hydrochloric acid Simple Procedure Place a conical flask on a piece of paper with a cross on it.
Add hydrochloric acid and sodium thiosulphate, and record the amount of time taken for the cross to disappear through the solution from the top of the flask.
