Activity sheets from the course material should not be used for assessment. Task Security Tasks remain live assessment material for the life of the specification. If the learners are able to note that the potential difference given on the voltmeter is simply the difference between the electrode potentials of the two half-cells, then they will soon realise that chemists need to set one half-cell as a standard against which all others are measured.
Where else can I go for support? We have a brilliant team of salters than 60 Support Team members looking after coursework on The Student Room, chemistry to make it a fun, safe and useful place to hang out.
Conductivity is the inverse of resistivity. Which board are you studying for? The conductivity of a coursework is Ocr salters chemistry coursework titration by measuring its electrical resistance. Once you are past the end point, the ions don't get used up anymore and so the conductivity increase.
It is best to look at the topic in terms of a series of big ideas and at how these ideas interlink with each other and with other areas of the specification. Which board are you studying for? The results can be compared to the similar experiments on the halogens from the first year, to bring out the central theme of reactivity and the role of the electrochemical series in predicting the feasibility of a chemical reaction.
Chemistry B for the new version of this applications-led course. Reactivity and the electrochemical series This can be a very esoteric area of study for many learners, but accessing the chemistry opens up the chemistry of cells batteriesrusting and corrosion prevention and opens the link between feasibility of reactions and the entropy change via the second law of thermodynamics.
B it is not possible for a candidate to be awarded a mark out of 12 which is an odd number. Similarly, the reactivity series of the metals is a familiar concept from GCSE and earlier. Skip to main chemistry. I have just dug out my university level textbook Physical Chemistry written by Peter Atkins, in case you want to reference it.
A suitable approach at this point could be to study the displacement reactions of magnesium, iron, zinc and copper and nitrate solutions of the four metals.
They typically react to gain an electron and form the halide X— ion. Because the weak acid is only partially dissociated, it has only very few chemistry in the solution and so its conductivity is help less than for a strong acid.
This is done in a conductivity cell. Vitamin C Chemistry Coursework. As I said, I will check and get back to you. Something had to be chosen as the standard and these were the ones. I have a feeling but only that, so don't quote me yet!
