Sodium Thiosulphate Rates of Reactions



During this research I am vent to study Sodium Thiosulphate the rates of
Reactions and which changes will affect this rate. A rate of reply
is when a reactant is lost or a new product is formed during a
Chemical reaction. I am expiration to investigate the effect of
Concentration by mixing Sodium Thiosulphate, Hydrochloric Acid and H2O
(Water) until the reaction takes issue and the mixture goes cloudy and
The newspaper beneath the flask back no longer be read. Both the Sodium
Thiosulphate and the Hydrochloric hot are soluble in water, so the
Concentration of either can be changed. However I am going to use
Varying amounts of Sodium Thiosulphate acid and H2O just I will keep
The amount of Hydrochloric Acid constant. This is heavy factor to
Investigate as the readings are recorded by human reactions, which
Could differ due to the inevitabilities of a human error.





fit to the collision theory of reacting particles there are five
various factors, which could affect this rate of reaction, these
are:

* Temperature

* The concentration of the solution

* The pressures of the gases

* The come out area if using solid reactants

* Catalysts

I predict that when I use the highest concentration of Sodium
Thiosulphate the reaction will draw much faster than when I use a
trim down concentration. I predict that there may be a pattern to the
results because the concentration is decreasing in equal amounts and
therefore the rate of reaction may do too. This is because for a
reaction to take place particles have to collide with an different solely
only a small percentage of these collisions result in a reaction. If
I increase the amount of particles then they are also more likely to
collide with each other and therefore the reaction should also occur
much faster, level off though the amount of successful collisions remain
the same.
