Resource
Finding the right ionic compound

Devise a procedure to identify four solids and then use this to carry out the identification.
Resource
Identifying four unknown solutions

Allow learner’s the opportunity to devise their own testing protocols to identify chloride ions in four solutions.
Resource
Find the pattern - alcohols

Consider data on the densities of six primary alcohols and solve four problems based on those data.
Resource
Find the pattern - metals

Consider data on the specific heat capacities for some metals and solve three problems related to those data.
Resource
Find the chloride

Devise experiments to determine which of five solids is the chloride by using chemicals and apparatus in the laboratory.
Resource
Which detergent is best?

Explain two observations related to the production of a jelly-like solid when two detergents were used in combination.
Resource
Cobalt 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.
Resource
Catalase enzyme reactions

Using four distinct questions, with open-ended methods, to explore catalysts and enzymes.
Resource
Empty 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.
Resource
Carbon and copper oxide

Create tests to identify carbon and copper oxide, using knowledge of acids, redox reactions, and metal oxides.
Resource
Measuring 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
Resource
Reacting aluminium foil with acid

React aluminium foil and hydrochloric acid with a range of catalysts to discover which serves the reaction best.
Resource
Defining a ‘weak’ acid

Starting from its K_a (or pK_a) value, learners calculate as much information as you need to show what is meant by ‘weak’ in weak acid.
Resource
Detecting copper in black solids

Devise experiments to identify a black solid sample by using chemicals and apparatus in the laboratory.
Resource
Identifying five unknown white solids

Learners are provided with five mystery white solids, and need to devise their own experiments to identify each.
Resource
Thin 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 ...
