A colloid is not a solution because...

• A colloid is a heterogenous mix with particles smaller than a suspension, but larger than a solution.

• a colloid is a homogenous mix of a solute and a solvent.

• a colloid is a homogeneous mix of undissolved particles.

A solution of salt water is ...

• homogeneous

• heterogeneous

• a suspension

• a colloid

A homogeneous mixture has ...

• components that are easily seen and sorted.

• components that are easily separated by settling filtration.

• components that do not separate or are spread out evenly throughout the mixture

• a concentration of solute in the mixture.

Choose all of the ways a mixture can be separated.

• Filtration: using a filter.

• Increase temperature for evaporation.

• Using a magnet.

• Picking item out by hand.
