A beaker contains a mixture of sand and salt. A student adds water to dissolve the salt. Which processes can be used to separate out the sand and salt?(1 point)

Answer 1

To separate the sand and salt from the mixture after dissolving the salt in water, the following processes can be used:

1. Filtration: The mixture can be poured through a filter paper in a funnel. The sand will remain on the filter paper (residue), while the saltwater solution (filtrate) will pass through.

2. Evaporation: After filtration, the salt can be recovered from the saltwater solution by evaporating the water. By heating the solution, the water will evaporate, leaving the salt crystals behind.

These two processes effectively separate the sand and salt from the mixture.
