Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the process of reduction?Dilution is the process of decreasing concentration, typically by adding more solvent
2. What is concentration in chemistry?Concentration is the amount of a substance compared to the total volume of the mixture. It tells us how much of one thing is in a solution.
3. How do scientists measure concentration?Scientists use different ways like mass concentration, molarity, number concentration, volume concentration, normality, and osmotic concentration. Each method looks at the mixture in a slightly different way.

Mass Concentration: The mass of a component divided by the total volume of the mixture.
Molar Concentration (Molarity): The amount of substance (in moles) of a solute per liter of solution.
Dilution: The process of reducing the concentration of a solute in a solution by adding more solvent.
