Describe how you would separate a mixture of sand, iron fillings and granulated sugar
To separate a mixture of sand, iron fillings, and granulated sugar, you can use a combination of physical separation techniques. Here's a step-by-step guide on how to do it:
1. Use a magnet: Since iron fillings are magnetic, you can use a magnet to separate them from the mixture. Pass the magnet over the mixture several times, and the iron fillings will be attracted to the magnet. Collect the iron fillings using a container.
2. Dissolve in water: Next, pour the remaining mixture (sand and sugar) into a container of water. The sugar will dissolve in water, while the sand will not. Stir the mixture to ensure the sugar dissolves completely.
3. Filtration: After the sugar has dissolved, use filtration to separate the sand from the liquid sugar solution. Set up a funnel with a filter paper or a fine mesh sieve over a separate container. Pour the mixture into the funnel, and the sand particles will be caught in the filter paper or sieve, while the sugar solution passes through.
4. Evaporation: To separate the sugar from the water, you can use evaporation. Place the container containing the sugar solution in a warm place or apply heat while ensuring you don't bring it to a boil. As the water evaporates, the sugar will crystallize and solidify on the container's sides or at the bottom.
5. Collect the sand and sugar: Once the water has completely evaporated, you'll be left with the sand and the crystallized sugar. Carefully scrape off the sugar crystals from the container and collect them. The sand can be collected from the filter paper or sieve used during filtration.
By following these steps, you should be able to separate the mixture of sand, iron fillings, and granulated sugar effectively.
