Microscale chemistry practicals
A number of the practicals and demonstrations featured on this page are based on experiments previously published in Microscale chemistry: experiments in miniature. Royal Society of Chemistry members receive a 35% discount at the RSC bookshop. Tips, ideas and practical experiments to bring microscale chemistry into your classroom, using only ...
Apparatus and techniques for microscale chemistry
Microscale experiments give students the opportunity to develop their observational and investigative skills using simple equipment and smaller quantities of chemicals. This practical guide is designed to accompany our Microscale chemistry resources, supporting you to use microscale experiments in your classroom. Find out about required ...
Little wonder: microscale chemistry in the classroom
Learn how to perform microscale experiments with droplets of reagents on plastic sheets or dishes, including electrolysis of sodium chloride or copper (II) chloride. Microscale chemistry improves safety, reduces waste, and enhances teaching and learning of chemical principles.
The fast guide to microscale practical work
Traditional practical work typically uses up to 100 cm 3 of gas, 1-50 g of solid and 10-100 cm 3 of liquid. For microscale activities, less than 100 cm 3 of gas, 1 g of solid or 0.5-1 cm 3 of liquid is needed. Microscale activities have been used for a long time and some of the activities have become standard practice, for example, doing ...

Microscale chemistry
Microscale chemistry. The range of school experiments being done on the microscale is growing. Reaction rates, relative atomic mass determinations and syntheses of organic and inorganic compounds, from Key Stage 3 through Key Stage 4 to A-level, are all proving to be successful. Experiments done on the millimolar scale are fast, safe and cheap ...
Microscale Chemistry
These experiments have been kindly donated by the Royal Society of Chemistry, originating from their publication Microscale chemistry, Experiments in Minature by John Skinner, the RSC Schoolteacher Fellow 1995-96. The experiments were developed as a means to carry out chemistry experiments on a reduced scale, using small quantities and often ...
Chemistry Education Through Microscale Experiments
Evidence is led from several different cases and countries that microscale experiments can achieve all the aims of practical work in chemistry but faster, cheaper, and more safely than traditional-scale experiments. Qualitative as well as quantitative experimentation can now bring modern techniques within the reach of all.
Quick quantitative chemistry
Quantitative chemistry allows students to generate experimental data and link it with their knowledge of particles, chemical equations, and numerical equations. This can be difficult for students to master and requires practice and familiarization with the equations and formulae involved. Microscale chemistry methods use less reagents, reduce ...
Innovative Techniques in Microscale Chemistry Experiments
They also serve as tools for better understanding chemistry principles. Three innovative techniques are highlighted here. 1."1248" Technique. An attractive experiment for determining the kinetic order of an "iodine clock" reaction can be redesigned using microscale 8-well reaction strips, the "shake-down" method, and the "1248 ...
Microscale Techniques
Learn how to perform organic chemistry experiments on a microscale level using special equipment and methods. This web page covers basic equipment, handling of liquids and solids, carrying out reactions, extractions, recrystallization and distillation.
Microscale chemistry
Microscale chemistry is an analytical and teaching method that uses small quantities of chemical substances. It can be applied to qualitative analysis, organic synthesis and lecture demonstrations, and has advantages such as saving time, reducing waste and cost.
Testing acids and bases on a microscale
See the accompanying guidance on apparatus and techniques for microscale chemistry, which includes instructions for preparing solutions. Sodium hydroxide, 1 mol dm -3. Hydrochloric acid, 1 mol dm -3. Sulfuric acid, 1 mol dm -3. Nitric acid, 1 mol dm -3. Sodium carbonate, 0.5 mol dm -3. Ammonia solution, 1 mol dm -3. Vinegar.
Microscale Chemistry : Experiments in Miniature
Microscale Chemistry is a book of such experiments designed for use in schools and colleges, and the ideas behind the experiments in it come from many sources, including chemistry teachers from all around the world. Current trends indicate that with the likelihood of further environmental legislation, the need for microscale chemistry teaching ...

'Named Small but Doing Great': An Investigation of Small-Scale
In theory, practical work is an established part of university-level chemistry courses. However, mainly due to budget constraints, large class size, time constraints and inadequate teacher preparations, practical activities are frequently left out from chemistry classroom instruction in most developing countries. Small-scale chemistry (SSC) experimentation in which one uses miniature chemical ...

Making nylon: the 'nylon rope trick'. The 'nylon rope trick' is a classic of chemistry classrooms, by mixing decanedioyl dichloride and in cyclohexane you can create a solution that will form nylon strings when floated on an aqueous solution of 1,6-diaminohexane. Kit list and safety instructions included.
