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

Explanation:

• Filtration: Sand is insoluble in water. When the mixture of sand - salt - water is filtered, the sand (as a solid residue) is collected on the filter paper.
• Distillation: Salt is soluble in water. After filtering out the sand, the salt - water solution is left. By distilling the salt - water solution, water evaporates (and can be condensed separately if needed) and salt (as a non - volatile solute) is left behind.

Answer:

filtration to collect the sand and distillation to collect the salt
