Edexcel Core practical guides for Combined Science Chemistry
NEW for SEPTEMBER 2017
The Scheme of Work relevant for each core practical is highlighted in square brackets e.g. [C2]

Core Practical 1 – C2.11 - Investigate the composition of inks using simple distillation and paper chromatography [C2]

Core Practical 2 – C3.6 - Investigate the change in pH on adding powdered calcium hydroxide or calcium oxide to a fixed volume of dilute hydrochloric acid [C8]

Core Practical 3 – C3.17 - Investigate the preparation of pure, dry hydrated copper sulphate crystals starting from copper oxide including the use of a water bath [C8]

Core Practical 4 – C3.31 - Investigate the electrolysis of copper sulphate solution with inert electrodes and copper electrodes [C10]

Core Practical 6 – C7.1 - Investigate the effects of changing the conditions of a reaction on the rates of chemical reactions by:
a) Measuring the production of a gas (in the reaction between hydrochloric acid and marble chips)
b) Observing a colour change (in the reaction between sodium thiosulfate and hydrochloric [C14]


Core Practical 1 – B1.6- Looking at cells

Core Practical 2 – B1.10 Investigate the effect of pH on enzyme activity

Core Practical 3 – B1.16 - Investigate osmosis in potatoes

Core Practical 4 – B6.5 - Investigate the effect of light intensity on the rate of photosynthesis

Core Practical 5 – B8.11 - Investigate the rate of respiration in living organisms

Core Practical 6 - B9.6 - Investigate the relationship between organisms and their environment using field-work techniques, including quadrats and belt transects
