The Effect of Acid on Sodium Thiosulphate
Aim: My Aim is to see how concentration of acid will affect the time
it takes for Sodium Thiosulphate to become cloudy and make a cross
below it to disappear.
Method:
Apparatus
Hydrochloric Acid
Sodium Thiosulphate
Distilled Water
250cm ³ Beaker- I need a beaker big enough to see the cross and
although the 100cm³ would be perfect volume wise I would prefer to use
a bigger one so I can fit the cross under it and also be able to pour
the reactants into it without any spillage
100cm ³ Measuring Cylinder- I have decided to use this cylinder for
the Sodium Thiosulphate. I am only using 50cm ³ each time but I would
prefer to use one in which I only have to measure to half way as
opposed to using a 50cm ³ Measuring Cylinder and having to measure it
right to the top. It will be easier to measure
10cm ³ Measuring Cylinder- This is the smallest Measuring Cylinder
available. I will use this to measure out the Hydrochloric acid and
Distilled water because there volume together will equal 10cm³. If I
use a 50cm³ Measuring cylinder, I won't be able to get a good enough
accuracy.
Stopwatch- For timing the experiment
Pipette for measuring out accurately and piping back excess
Hydrochloric acid
Piece of paper with a black cross on it like this: To find out when
the experiment has ended. It is dark and thick because I want to
clearly see when the experiment has finished
Paper towels: For washing beakers and measuring cylinders out.

2. Put the black cross underneath the 250cm ³ Beaker, leave this on
the side.
3. Measure out 50cm ³ of Sodium Thiosulphate in the 100cm ³
Measuring cylinder and pour into the 250cm ³ beaker
4. In the other 100cm ³ measuring cylinder.
The Effect of Acid on the Neutralisation Point Aim to find how the concentration of acid affects the neutralisation point between acid and alkali. Preliminary work in my preliminary work my aim was to find out which indicator would give the best results in my neutralisation experiment to do this we used three different indicators and worked out which one gave us the result closest to the neutralisation point. We found that universal indicator gave us the most varied results and was the closest to the neutralisation point. Prediction I predict that the higher the concentration of the acid the more alkali will be needed to neutralise the acid. Hypothesis an equal amount of the same strength acid and alkali will neutralise each other, so if there is 100ml of 1 mole acid and 100ml of 1 mole alkali mixed together the solution would become neutral.
* Concentration - I will try my best to use all the acid from the

The Effect of Sodium Thiosulphate Solution on the Rate of its Reaction with Hydrochloric Acid
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.
For my preliminary work, I used a 50 mm piece of potato. It was easy
from 10cm to 50cm to make it easier to see the difference in a graph.
Sodium Thiosulphate and Hydrochloric Acid Reaction Investigation Aim To see the effects of concentration on the rate of a reaction between sodium thiosulphate and hydrochloric acid. Background information The collision theory briefly: For a reaction to occur particles have to collide with each other. Only a small percent result in a reaction. This is due to the energy barrier to overcome. Only particles with enough energy to overcome the barrier will react after colliding.
anything and roughly measure marks approximate to house location, this way you would have a
By analysing the results it could be seen that there was a relationship between the concentration of sodium thiosulfate and the time take for the cross to be no longer visible on the white tile through the solution. From graph 1 it could be seen that the concentration of sodium thiosulfate and the time taken for the reaction to be completed are inversely proportional, as when the concentration of sodium thiosulfate increases, the time taken decreases and the graph levels out as it approached the x-axis. Graph 2 supports this by showing that the concentration of sodium thiosulfate and the rate of the reaction share a linear relationship, meaning that the concentration is directly proportional to the inverse of the time taken.
My aim in this piece of work is to see the effect of temperature on the rate of a reaction in a solution of hydrochloric acid containing sodium thiosulphate.
Rate of Reaction - Sodium Thiosulphate and Hydrochloric Acid. Aim Investigation, to find out how the rate of reaction between sodium thiosulphate and hydrochloric acid is affected by changing the concentration. Introduction I must produce a piece of coursework investigating the rate of reaction, and the effect different changes have on them. The rate of reaction is the rate of loss of a reactant, or the rate of development of a product during a chemical reaction. It is measured by dividing 1 by the time taken for the reaction to take place.
