The correct answer is: filtration to collect the sand and distillation to collect the salt.
Explanation:
- Filtration: The mixture can be poured through a filter paper in a funnel. The sand, being insoluble in water, will remain on the filter paper, while the saltwater solution will pass through.
- Distillation: The saltwater solution can then be heated. The water will evaporate, and as it condenses, it can be collected separately, leaving the salt behind.
Thus, this combination effectively separates both components of the mixture.
