Ways to Separate a Mixture of Sand, Iron Filings, and Sugar

To separate a mixture of sand, iron filings, and sugar, there are several methods that can be used. The three methods mentioned in the question are:

A. Dissolving in water: This method takes advantage of the fact that sugar is soluble in water, while sand and iron filings are not. By adding water to the mixture and stirring it, the sugar will dissolve, leaving behind the sand and iron filings. The mixture can then be filtered to separate the sand from the iron filings. The sugar solution can be further processed to recover the sugar.

B. Evaporation: This method can be used to separate the sugar from the mixture. After dissolving the sugar in water as described in method A, the water can be evaporated using heat. As the water evaporates, the sugar will crystallize and can be collected separately. The sand and iron filings will remain behind.

C. Magnetic separation: This method can be used to separate the iron filings from the mixture. Iron is a magnetic material, while sand and sugar are not. By using a magnet, the iron filings can be attracted and separated from the mixture. This can be done by passing a magnet over the mixture or by using a magnet to attract the iron filings while the mixture is in a container.

It's important to note that these methods are just a few examples of how to separate the mixture. There may be other methods depending on the specific characteristics of the mixture and the desired outcome.
