The reaction between sodium thiosulphate and HCL
Aim - The aim of this experiment was to find out the rate of a reaction at different temperatures.
- We also wanted to find out the rate of the reaction at a different temperature in bigger or smaller surface areas.
Prediction - My prediction is, by increasing the temperature a reaction will happen more quickly.
The more heat - The Faster reaction and more collision.
The lower the temperature - The slower the reaction and less collision. GRAPH
My Understanding
Reactions occur at different speeds in different temperatures.
I’ve learnt that if the temperature is high reactions will take place much more quickly and the particles will collide more often.
The table and graphs prove my theory.
The Calculator was used for calculating the average of the times that was recorded for the reactions to happen.
The Beaker was used to mix the chemicals for the reaction to take place. The Stop watch was used for timing how long it took for the reaction to happen.
Method
- For this experiment I first set up the apparatus with the apparatus that is shown above.
- I then poured 5lm of HCL into a conical flask.
- I then measured 10 ml of sodium thiosulphate,
- I then I added it to the 5 ml of HCL.
- I recorded how long it took for the reaction to take place, which was how long it took for the X to disappear.
- With the times that I recorded from the experiment, I calculated an average. - I then repeated the experiment at 3 different temperatures.
Factors and Fair Test
To make this a fair test I:
- Kept the amount and concentration of the chemicals the same.
- Varied the temperatures to find out how long it would take for a reaction to happen at different temperatures
- Did each experiment at each temperature three times to make the experiment more fair. I also calculated an average, this reduces any anomalous data.
Conclusion
- My results show that the hotter the reactants the faster the reaction. - This happened because the particles move more quickely and collide more often as stated in the collision theory.
- The experiment proved my prediction correct which was based upon the
One of the best methods for determining mass in chemistry is gravimetric analysis (Lab Handout). It is essentially using the the mass of the product to figure out the original mass that we are looking for. Thus the purpose of our experiment was to compare the final mass in our reaction to the initial mass and determine the change in mass.
How am I going to make it a fair test I will use a clean flask for
have either not stir the mixture or use a machine to stir it at the
Possible sources of error in this experiment include the inaccuracy of measurements, as correct measurements are vital for the experiment.
Investigation of How Temperature Affects the Rate of Reaction of Sodium Thiosulphate and Hydrochloric Acid
Experiment is to investigate the rate of reaction between hydrochloric acid and calcium carbonate Hydrochloric acid + Calcium Carbonate Þ Calcium Chloride + Water + Carbon Dioxide 2HCl (aq) CaCo3 (s) CaCl2(s) H2O (aq) CO2 (g) There are a number of variables in this experiment and these are listed below as input variables and outcome variables.

The Effects of Concentration on Reaction Rate with Sodium Thiosulphate ---------------------------------------------------------------------- Planning = == == =
Before conducting my experiment I will research into, amongst other things, the factors that affect the rate of a reaction. This is so that I may enough information to understand the effect of temperature on the rate of a reaction and also gain appropriate understanding to make a suitable prediction as to what the outcome of my experiment will be.
Effect of Temperature on the Rate of Reaction between Sodium Thiosulphate and Hydrochloric Acid Investigation Chemical reactions are used in our everyday life, they literally keep us alive. They are used in food, respiration and everywhere else in the environment. A chemical reaction mainly occurs when reactants react together to produce a new product. The speed at which this reaction takes place is called the rate of reaction. The product produced has a number of particles in the solution that has formed from the reactants.
Rates of Reaction - Sodium Thiosulphate and Hydrochloric acid In this piece of coursework, I will study how concentration affects the rate of reaction. I will do so by timing the reaction of Sodium Thiosulphate with an acid. In this coursework, I will include background knowledge, prediction, safety, results, calculations, graphs, an analysis, conclusion and an evaluation. In my evaluation I will comment on how reliable my results were and how I could have improved my coursework in any possible way.
My aim is to see the effects of a change in temperature on the rate of
