which physical method can be used for obtaining a sample of salt from a small beaker of salt water? boiling freezing chromatography sorting
Answer
Brief Explanations:
Boiling salt - water causes the water to evaporate as steam, leaving the salt behind. Freezing separates components based on different freezing points, not suitable here. Chromatography separates mixtures based on different affinities for a stationary and mobile phase, not applicable for salt - water separation. Sorting is used for separating solid - solid mixtures by physical characteristics, not for salt - water.
Answer:
A. boiling
