Essay text:
So the following procedure can be used
to carry out the experiment.
Plan
Equipment
? 2 Measuring cylinders
? Beaker
? Stopwatch
? Paper with black cross on it
? Sodium Thiosulphate (different concentrations)
? Hydrochloric acid (same concentration each time)
? Water (different concentrations)
? Pipette
Prediction
I predict that the greater the concentration of Sodium Thiosulphate
solution the faster the chemical reaction will take place... Showed first 250 characters

Therefore,
the cross will disappear more quickly due to the cloudiness of the
solution. I predict that as concentration is doubled the amount of
time taken for the reaction is halved. This means that both graphs
drawn up in my analysis will have positive correlation, and will
probably be curved as the increase in rate of reaction will not be
exactly the same as the concentration is increased... Showed next 250 characters

Rates of Reaction
Aim:
To find out how different concentrations of sodium thiosulphate (Na S2 O3) affects the speed of its reaction with Hydrochloric acid (HCL).
Introduction
When Sodium Thiosulphate and Hydrochloric acid react they produce a cloudy precipitate... |

preliminary results
Sodium + Hydrochloric Sulphur + Sulphur + Water + Sodium
Thiosulphate acid Dioxide Chloride
Na2S2O3 + 2HCl S + SO2 + H2O + 2NaCl
As you can see from the word equation there are a lot of bonds to break in this experiment so the more "HCl's" there are the quicker it will be to break the Sodium Thiosulphate... |

What Effect The Concentration Of Acid Has On The Rate Of Reaction
Aim
The aim of this experiment is to find out what effect concentration has on a rate of reaction.
Prediction
I predict that the higher the concentration of the acid, the faster the reaction will take place, this is because when there is a higher concentration, to a certain extent, there is more particles, so the higher the concentration of acid, the more particles there would be, so these particles will have more chance of colliding with each other, which is what causes the reaction... |

Rates Of Reaction
Aim: An experiment to determine if changing the concentration of a reactant alters the rate of reaction.
Plan and Method
In the experiment we are going to undertake, we have to add to concentrates into a chronicle flask that have been very carefully measured to 10ml... |
