Making a Solution

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

Define Concentration

• It is the ratio of the amount of a "solute" compared to the amount of a "solvent" in a solution.

• It is the ratio of the amount of a "solvent" compared to the amount of a "solution" in a "solute"

• It is the ratio of the amount of a base substance compared to an acid substance in a solution.

• It is the ratio of the number of "moles" in a solution compared to the "molarity".
