ResourceFind the pattern - metals
Consider data on the specific heat capacities for some metals and solve three problems related to those data.
-
ResourceFind the pattern - alcohols
Consider data on the densities of six primary alcohols and solve four problems based on those data.
-
ResourceFind the chloride
Devise experiments to determine which of five solids is the chloride by using chemicals and apparatus in the laboratory.
-
ResourceCobalt complexes
Devise structures for cobalt complexes given, decide how to distinguish between the four complexes, and identify some properties that are the same for all four complexes.
-
ResourceWhich detergent is best?
Explain two observations related to the production of a jelly-like solid when two detergents were used in combination.
-
ResourceCatalase enzyme reactions
Using four distinct questions, with open-ended methods, to explore catalysts and enzymes.
-
ResourceCarbon and copper oxide
Create tests to identify carbon and copper oxide, using knowledge of acids, redox reactions, and metal oxides.
-
ResourceEmpty space in gaseous argon
How much ‘empty space’ is in a sample of gaseous argon? Students use their knowledge of Avogadro’s number and the concept of atomic size to find out.
-
ResourceMeasuring CO2 from reactions
Use chemicals and apparatus, devise experiments and determine the amount of carbon dioxide that can be obtained from a mixture of two solids
-
ResourceReacting aluminium foil with acid
React aluminium foil and hydrochloric acid with a range of catalysts to discover which serves the reaction best.
-
ResourceDefining a ‘weak’ acid
Starting from its Ka (or pKa) value, learners calculate as much information as you need to show what is meant by ‘weak’ in weak acid.
-
ResourceDetecting copper in black solids
Devise experiments to identify a black solid sample by using chemicals and apparatus in the laboratory.
-
ResourceIdentifying five unknown white solids
Learners are provided with five mystery white solids, and need to devise their own experiments to identify each.
-
ResourceThin layer chromatography
The technique of Thin Layer Chromatography (TLC) is normally used as an analytical method to follow the progress of a reaction, to analyse mixtures or to establish conditions for a preparative separation of compounds using column chromatography. The stationary phase (often silica) is coated on plastic or aluminium plates. The ...

ResourceOn This Day – Jul 07 : Rocket apparatus fueled with solid 'explosive material'
The first of these rockets was successfully launched on 16th March 1926 by the American scientist and his colleagues in Auburn, Massachusetts. It was fuelled by liquid oxygen (O2) and gasoline, and reached a height of 12.5 metres.

ResourceColumn chromatography
The separation of mixtures produced in chemical reactions is often carried out by passing the mixture through a stationary phase of silica held in a column. Solvents move compounds at different rates through the silica allowing them to be separated into fractions by collecting the emerging solvent. This can ...
