In Michael's science experiment with salt water, NaCl (salt) would be considered the ______.

• Solution

• Solute

• Solvent

• Solvation

Kool-Aid - Powder, sugar, and water
Identify the solvent 

• water

• powder

• sugar

• powder and sugar

Answer explanation

The solvent in Kool-Aid is water, as it is the substance that dissolves the powder and sugar to create the drink.

What is a solvent

• A liquid that will dissolve a solid solute

• Another word for solution

• A thing that make drinks change colour

• Usually the solid about to be dissolved

What does it mean when a solution is dilute?

• low or weak concentrated solution

• high or strong concentrated solution

• solution that will react with dark metals

• solution that will react with light metals

What is the main difference between a solution and a mixture?

• Solutions can only be liquids, while mixtures can be in any state of matter

• Solutions are always clear, while mixtures are cloudy

• Solutions are homogeneous, while mixtures can be heterogeneous

• Mixtures can be separated by physical means, while solutions cannot

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.
