The Effect of Sodium Thiosulphate Solution on the Rate of its Reaction with Hydrochloric Acid
Aim
I shall investigate how the concentration of Sodium thiosulphate
solution affects the rate of its reaction with hydrochloric acid.
I shall add water to the sodium thiosulphate solution to weaken the
concentration so I can see how concentration can affect the rate of
reaction.
I shall add water as that is the only way I can find out how
concentration affects the rate of reaction as I cannot increase
concentration from 1M upwards as I do not have the resources available
to use.
[IMAGE]Prediction
I predict that when I add more water to the sodium thiosulphate
solution, the time it takes for the cross to disappear will lengthen.
[IMAGE]I predict this because, for particles to react they must
collide with each other. If there is a higher concentration of sodium
thiosulphate particles in a given volume there is a higher chance of
the particles colliding together and reacting. This is because they
are so close together. If you weaken the solution, (so there is a much
lower concentration of sodium thiosulphate particles to react with the
hydrochloric acid,) then there is less chance of the particles
colliding and reacting as there are less particles in the given
volume, so the reaction time will slowly lengthen as the concentration
goes down.
[IMAGE]My graphs should hopefully look like this.
Plan
Factors to control
I shall have to control as many aspects of the experiment as possible,
to make it a fair test.
I shall make sure the total volume of the solution stays the same. I
shall do this by reducing the volume of sodium thiosulphate as I add
water, the total volume of the sodium thiosulphate solution and water
will be 50cm3. An example would be having 30cm3 of sodium thiosulphate
and having 20cm3 of water, added together their volume is 50cm3.
I shall do this because if I did not then the total volume would go up
Investigating How the Concentration of Hydrochloric Acid Affects the Rate of Reaction with Calcium Carbonate
Rate of reaction is the speed of reaction. In essays written by young scientists, they have used concentration as variable in their experiments; some have used a light sensor. connected to a data logger, to measure the amount of light passing. through the "cloudy" liquid. 1 moles = 6.02 1023 The particles in the hydrochloric acid and sodium thiosulphate need to

The Effect of Temperature of Hydrochloric Acid on the Rate of Reaction Between Hydrochloric Acid and Magnesium
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.

The Effect of Concentration of Hydrochloric Acid on the Rate of Reaction with Magnesium Aim: To investigate the effect of concentration of hydrochloric acid on the rate of reaction with magnesium Prediction: As the concentration of the hydrochloric acid increases, so will the rate of reaction Hypothesis: In a reaction, particles of two different reactants react together to form a product. The reaction only takes place on account of two things, if the particles collide, and if the collision has enough 'activation energy'. The two reactant particles, in this case magnesium particles and hydrochloric acid particles, must collide with each other on the correct 'collision course'. If this does not occur then no chemical reaction will take place. The reaction must also have enough energy, this can be affected by temperature, the more heat the particles have the faster they move and so the more energy therefore more chance of successful collisions.
Conclusion This experiment was set out to find the effect of different temperatures of hydrochloric acid on the rate of reaction with magnesium. The information recorded was then interpreted and compared to the hypothesis. From this information, a conclusion can be made to show that the rate of reaction relates to temperature in the reaction between hydrochloric acid and magnesium. In conclusion, as proven in this experiment, the higher the temperature of hydrochloric acid, the faster the reaction it has with magnesium.

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.
