Question

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

a filtration
b magnetic attraction
c evaporation
d chemical reaction

Explanation:

• Filtration is used to separate solids from liquids when the solid is insoluble. Salt is soluble in water, so filtration won't work.
• Magnetic attraction is for separating magnetic substances. Salt and water are non - magnetic.
• Evaporation can be used. When saltwater is evaporated, the water turns into vapor and leaves the salt behind.
• A chemical reaction is not needed here as we are just separating a mixture, not changing the chemical composition of salt or water through a reaction.

Answer:

C. Evaporation
