Question

A beaker contains a mixture of sand and salt a student adds water to dissolve the salt which process can be used to separate out the sand and salt

Answer 1

To separate the sand and salt from the mixture after dissolving the salt in water, you can use the following process:

1. **Filtration**: Pour the mixture through a filter paper placed in a funnel. The sand, which does not dissolve in water, will remain on the filter paper, while the saltwater solution will pass through the filter and collect in a separate container.

2. **Evaporation**: After filtration, you will have a saltwater solution in the container. To recover the salt, you can heat the solution to evaporate the water. As the water evaporates, salt crystals will be left behind.

By using these two methods, you can effectively separate the sand and salt from the mixture.
