hana fills a cup with sandy ocean water. she pours the mixture through a filter. what does she collect that passes through the filter?\n a sample of pure water\n a solution of salt in water\n a suspension of sand in water\n a colloid of salt in water
Answer
Brief Explanations:
Ocean water contains salt and sand. A filter can remove sand (a suspension) as sand particles are large - sized. But it cannot remove dissolved salt. So what passes through is a solution of salt in water. Pure water would require more advanced purification methods like distillation. A colloid has particles of intermediate size between solutions and suspensions, and salt in water is a true solution, not a colloid.
Answer:
B. a solution of salt in water
