Question

1. how can a saltwater solution be separated into its components?

a magnetic attraction
b chemical reaction
c evaporation
b filtration

Explanation:

• Magnetic Attraction: Used for separating magnetic substances from non - magnetic ones. Saltwater components (salt and water) are not magnetic.
• Chemical Reaction: Changes the chemical composition. We just want to separate salt and water, not change their chemical nature.
• Evaporation: Water evaporates (changes to vapor) when heated, leaving salt behind. This is a physical separation method suitable for saltwater.
• Filtration: Used to separate solids from liquids when the solid is insoluble. Salt is soluble in water, so filtration won't work.

Answer:

C. Evaporation
