A sample of sucrose as been contaminated with sand.How would you purify the sucrose
Dissolve in water and decant or off the liquid solution, possibly centrifuging first. Distill away the water from the solution if necessary.
To purify the contaminated sample of sucrose, you can follow the process of filtration. Here's how you can do it step by step:
1. Preparation: Gather the necessary materials, including a funnel, filter paper, a beaker, and a clean container.
2. Set up the filtration apparatus: Place the funnel on top of the beaker. Fold the filter paper into a cone shape and place it inside the funnel, ensuring that it fits securely. Make sure there are no gaps where the liquid could pass through without being filtered.
3. Wet the filter paper: Pour a small amount of distilled water over the filter paper. This will help it adhere to the funnel and prevent any gaps.
4. Pour the contaminated sucrose solution: Carefully pour the contaminated sucrose solution into the funnel. The liquid will pass through the filter paper, while the sand particles will be trapped.
5. Collect the purified sucrose solution: The filtered sucrose solution will drip into the beaker below. Allow it to pass through until all the liquid has been filtered.
6. Transfer the purified solution: Carefully pour the purified sucrose solution from the beaker into a clean container. Make sure to avoid pouring any sediment that may have settled at the bottom of the beaker.
7. Evaporation (optional): If you want to remove any remaining water and obtain solid sucrose, you can evaporate the purified solution. Pour the solution into a shallow dish and leave it in a well-ventilated area, or gently heat it, to allow the water to evaporate. The sucrose crystals will remain in the dish once all the water has evaporated.
By following these steps, you should be able to effectively purify the contaminated sample of sucrose and separate it from the sand.
