How do you separate sand from salt in a homogeneous expeiriment?
Add water to dissolve the NaCl, pour through a filter paper. The sand will be in the paper. Dry to recover the sand. Evaporate the water separately to recover the NaCl.
To separate sand from salt in a homogeneous mixture, you can follow these steps:
1. Add water: Pour the mixture of salt and sand into a container and add water. Stir the mixture thoroughly to dissolve the salt. Note that salt is soluble in water, while sand is not.
2. Filter the mixture: Set up a filtration apparatus by placing a filter paper in a funnel, and place the funnel in a separate container to collect the filtrate. Pour the mixture through the filter paper to separate the sand from the saltwater solution. The sand particles will be trapped in the filter paper, while the saltwater solution will pass through.
3. Dry the sand: Remove the filter paper with the sand particles and allow it to dry naturally or use an oven or heating device to speed up the drying process. Once dried, you will have purified sand.
4. Recover the salt: Take the container with the saltwater solution collected from filtration and transfer it into a glass or shallow dish. Leave the dish in a well-ventilated area or use a gentle heat source to evaporate the water. As the water evaporates, salt crystals will begin to form. Once all the water has evaporated, you will be left with pure salt crystals.
Remember, the process of separating sand from salt in a homogeneous mixture involves dissolving the salt in water, filtering out the sand particles, and then recovering both the sand and salt individually by drying and evaporating, respectively.
