Analytical chemistry – pupil resources

This collection of classroom resources features all the pupil activities from our Developing expertise in teaching analytical chemistry course for teachers. This collection is most valuable to those who have attended this course and wish to put into practice with their students some of the ideas and activities presented as part of that event.

Elements, compounds and mixtures

Chemistry is a conceptual subject and, in order to explain many of these concepts, teachers use models to describe and explain the microscopic world and relate it to the macroscopic properties of matter. This resource is designed to provide strategies for dealing with some of the misconceptions that students have ...

Separating sand and salt

In association with

In this experiment students separate a mixture of sand and salt. This illustrates the fundamental meaning of separating an insoluble material from one which is soluble.

Mass and dissolving

Chemistry is a conceptual subject and, in order to explain many of these concepts, teachers use models to describe and explain the microscopic world and relate it to the macroscopic properties of matter. This resource is designed to provide strategies for dealing with some of the misconceptions that students have ...

The fractional distillation of crude oil

In association with

This experiment simulates the industrial fractional distillation of crude oil in the laboratory.

Image

Chromatography of leaves

In association with

Separate the different pigments present in a leaf using paper chromatography.

Image

Chromatography worksheet

This activity extends the students’ understanding of chromatography. It links chromatography with particle theory and develops the tools of analogy and modelling.

Image

Flame tests (the wooden splint method)

The method described in this experiment is intended for students to carry out and avoids the need for the use of concentrated hydrochloric acid. It also avoids the cost and contamination problems associated with the use of nichrome or platinum wires.

Testing salts for anions and cations

Learn how to identify the composition of unknown substances

Image

Chromatography

This book teaches about modern chemical techniques without heavy emphasis on maths or physics. It includes descriptions of instruments and their applications.

Image

Aspirin book

This book contains eight free-standing activities that can be used singly or as a coherent package in a wide range of teaching and learning situations for both academic and vocational courses.

Finding the formula of hydrated copper(II) sulfate

In association with

In this experiment, the water of crystallisation is removed from hydrated copper(II) sulfate. The mass of water is found by weighing before and after heating. This information is used to find x in the formula: CuSO4.xH2O.

Brass instruments

The determination of copper in brass

Investigate how much copper there is in brass (an alloy of copper and zinc) by dissolving the brass in nitric acid and comparing the colour of the solution with that of solutions of various concentrations of copper

Image

Melting point determination

The measurement of melting points is a relatively straightforward procedure that is carried out to determine the purity of a compound or to assist with its identification. A pure compound will melt over a relatively narrow temperature range, impurities both lower and widen the temperature range over which a compound ...

Recovering water from copper(II) sulfate solution

In association with

In this experiment, water from copper(II) sulfate solution is evaporated and some of it is condensed using simple apparatus.

electromagnetic radiation

Introduction to spectroscopy

Get back to basics with this primer on the principles of spectroscopic techniques, including infrared (IR), ultraviolet-visible (UV-vis) and nuclear magnetic resonance (NMR). To make it even easier, each technique has clear explanations and descriptions supported by animations.

Spectroscopy in a Suitcase students' resource: spectroscopy introduction

Spectroscopy is the study of the way light (electromagnetic radiation) and matter interact. There are a number of different types of spectroscopic techniques and the basic principle shared by all is to shine a beam of a particular electromagnetic radiation on to a sample and observe how it responds to ...

Spectroscopy in a Suitcase: IR student resources

One of the first scientists to observe infrared radiation was William Herschel in the early 19th century. He noticed that when he attempted to record the temperature of each colour in visible light, the area just beyond red light gave a marked increase in temperature compared to the visible colours. ...

mass spectrometer

Mass spectrometry (MS)

Mass spectrometry is a powerful technique in the modern analytic laboratory. Learn the fundamental theory behind the operation of a mass spectrometer.

Oxygen cylinder

Gases from Air

In association with

An introduction to extracting gases from air.
