In this experiment the soluble salts are magnesium sulfate and sodium carbonate, and the insoluble salt formed is magnesium carbonate, which can be filtered, dried and collected.

This is a short standard class experiment. It should take no more than 20 minutes to the point at which the wet product can be set aside to dry. If the solutions can be provided in pre-measured 25 cm 3 quantities in labelled containers, distribution of chemicals and control of quantities can be easily managed, and the practical work can begin without delay.

Sodium carbonate in dilute solution is weakly alkaline. So the few other safety issues are essentially restricted to safe handling of glassware. Even these can be minimised by the use of polythene filter funnels. This experiment is therefore suitable as a class experiment for most classes. There are no significant hazards in this experiment, except for the risk of broken glass if a flask is knocked over.

The formation of precipitates on mixing two solutions is met frequently in chemistry. This experiment is intended as a first introduction to this phenomenon for 11—14 year olds, as well as to practical filtration techniques. The experiment can be made more exciting visually by making a coloured salt such as copper II carbonate; in this case the chemical hazard level is slightly higher, since copper II carbonate is HARMFUL.

Because this is intended as a first introduction, the interpretation should be restricted to developing the word equation as a summary of what has happened:. Suggesting the name of the salt left in solution is not easy for students at this stage. It needs to be approached carefully, probably by group or whole class discussion.

You could add some interest to which salts are used, and which salts are formed. Mention their uses, if this helps the class to see that these substances are not just important in the laboratory. See below. Magnesium sulfate is known as Epsom salts.

This is because the water found at the spa at Epsom in Surrey contains this salt in quite high concentration. Epsom salts are rarely used nowadays, but were used in medicine as a purgative. Sodium carbonate is found naturally in high concentrations in the soda lakes of Kenya and Tanzania in East Africa.

It is also manufactured in vast quantities and used in many different industries, including the chemical industry itself and in glass making. It is found in the home as washing soda, and in some detergent powders. For more about sodium carbonate in general, you may be interest in the Royal Society of Chemistry Book, Sodium carbonate: a versatile material.

Magnesium carbonate is found in the mineral dolomite, mixed with calcium carbonate. Most limestones contains a proportion of magnesium carbonate — some a very high proportion. Magnesium carbonate is used in industry as a major source of magnesium compounds, it is used in many medical preparations to treat indigestion and it is also used as gym chalk. It is used in large quantities in industries such as wood pulp production, glass-making, and detergents, and is also as a mild laxative.

If this experiment is used with older students, you can ask them to work out the symbol equation:. However, this is not likely to be the experiment where the concept of spectator ions is introduced, as there are better examples, with visual colour clues to what is happening. The ionic equation is:. This collection of over practical activities demonstrates a wide range of chemical concepts and processes. Each activity contains comprehensive information for teachers and technicians, including full technical notes and step-by-step procedures.

Making magnesium carbonate: the formation of an insoluble salt in water. No comments. Equipment Apparatus Eye protection Conical flasks cm 3 x2 Filter funnel 65 mm diameter or similar, note 1 Filter papers size suited to funnels used Apparatus notes Polythene filter funnels are safer and cheaper than glass funnels.

The size of filter paper, when folded, should match the funnel size. The cheapest grade of filter paper is okay for this experiment.
