Question

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) Responses filtration to collect the sand and distillation to collect the salt filtration to collect the sand and distillation to collect the salt distillation to collect the sand and filtration to collect the salt distillation to collect the sand and filtration to collect the salt filtration to collect both the sand and the salt filtration to collect both the sand and the salt distillation to collect both the sand and the salt distillation to collect both the sand and the salt

Answer 1

The correct processes to separate out the sand and salt from the mixture in the beaker are filtration to collect the sand and distillation to collect the salt.

• Filtration will be used to separate the undissolved sand from the saltwater solution; the sand will be retained on the filter paper while the saltwater passes through.
• Distillation can then be used to separate the salt from the water in the saltwater solution. By heating the solution, the water will evaporate, leaving the salt behind.

So the best answer is: filtration to collect the sand and distillation to collect the salt.
