The correct process to separate out the sand and salt in this situation is:
filtration to collect the sand and distillation to collect the salt.
Here's the reasoning:
- When water is added to the mixture, the salt dissolves in the water, while the sand does not.
- Filtration can be used to separate the sand from the salty water: the sand will remain on the filter paper, and the saltwater solution will pass through.
- After filtration, the salt can be recovered from the salty water by distillation, where the water is evaporated, leaving the salt behind.
Thus, the best answer is: filtration to collect the sand and distillation to collect the salt.
