Investigating How Changing the Concentration of Hydrochloric Acid Affects the Rate of Reaction with Sodium Thiosulphate Solution
Aim
I aim to investigate how changing the concentration of Hydrochloric
acid affects the rate of reaction with Sodium Thiosulphate solution.

The reaction makes the solution go a yellow cloudy colour and a gas is
given off.
Procedure
To ensure that our results are precise accurate and reliable we are
going to take more than one set of results down and we will do the
test twice. If there appears to be a set of results that does not fit
the pattern we will repeat the test that it occurred in. We will also
make sure that the apparatus we are using gives an accurate
measurement. Also, in order to keep it a fair test, we will keep all
of the variables the same, except from one. This will be the distilled
water. We will use the same cross throughout the experiment. Otherwise
the shade of the cross could be different so it may take a different
period of time for the cross to totally disappear. To ensure that we
use the right amount of sodium thiosulphate and the same amount of
hydrochloric acid, we will use a pipette.
Investigation to find out if changes in concentration of acid affect the rate of a chemical reaction
We will set up a conical flask on top a cross. We will vary 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.
from 10cm to 50cm to make it easier to see the difference in a graph.
Investigating How the Concentration of Hydrochloric Acid Affects the Rate of Reaction with Calcium Carbonate
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.
