distillation to collect the sand and filtration to collect the salt

1 answer

The correct response is:

filtration to collect the sand and distillation to collect the salt.

Here's why:

  1. Filtration can be used to separate the sand from the mixture because sand particles are larger and will be retained by the filter, while the salt (dissolved in water) will pass through.

  2. Distillation is used to separate the dissolved salt from the water. When the water is heated, it will evaporate, leaving the salt behind, and the steam can be collected and cooled to condense back into liquid water if desired.

Thus, the first option correctly identifies the appropriate techniques for separating sand and salt from the mixture.
