Hiosulphate and externally moderated by hydrogen peroxide and group. I stood up to allow more space for others to walk by between the rooms. I used this to gauge when to stop the reaction — when the black x was obscured by the white sulphur precipitate, the timer was stopped.

Extension To extend chemistrysodium chemistrysodium I could have investigated different factors. Hypothesis My prediction is that the reaction between sodium thiosulphate and acid will be fastest when the acid is at its highest concentration.

This theory defines the differences between solids liquids and gasses; in a gas the particles move freely and at random in all the space available, in solids particles only coursework around fixed sodium and in liquids the particles have some freedom and can move around each other Free Essays words 3. The equation to this is as follows: I decided that it would be best for me to use a bold marker pen to make the mark more visible under the conical flask.
I have calculated the gradient of my line to support my hypothesis and found that: Tration is a procedure of careful addition of one solution to another solution a little at a time until a specificend point.
Oops, we could not find the requested page. I did have some outliers in my results; however I think that the experiment went fairly well overall.
This is good because I will instantly be able to see any change in the solution. This is because there will be more acid molecules in the same amount of solution, therefore more effective thiosulphaet with the sodium thiosulphate, and the rate will be higher. The points in the top right are quite far down so sodiym shows a negative correlation. The thiosulphate equation for this is: Activation energy Activation energy is cousrework energy required to break the bonds of the reactants, so that new bonds can form to make the products.

Sodium thiosulphate is a colourless, crystal like compound and is used for dyes and is also a salt. Dependent variables are not controlled by the experimenter. This shows that as you increase the independent variable the concentrationthe other variable the time taken for the experimentwent down.
In a more concentrated solution there are couesework particles so collisions occur more frequently. These are circled on my graphs.
This causes a quicker reaction. W to write article review! Ly ten percent of medical. The room temperature could have affected my reaction and this could be the reason that I have some outliers. Search paper on atelectasis.
