How to Dilute a Solution

The video tutorial by Svenja Luna from Science Buddies explains how to dilute a solution or sample. It covers the basic concept of dilution, methods to dilute solutions, and how to calculate the concentration of a diluted solution using an equation. The video also explains dilution ratios and factors, providing practical examples, such as making a 1 to 5 dilution of a Kool-Aid solution. The tutorial aims to equip viewers with the knowledge to handle dilution challenges in science projects.

What is the simplest way to dilute a solution?

• Increase the temperature of the solution

• Remove some solute from the solution

• Add more solvent to the solution

• Add more solute to the solution

What is the term used for the original solution used to make a dilution?

• Base solution

• Primary solution

• Stock solution

• Initial solution

If you mix 100 ml of a solution with 100 ml of water, what happens to the concentration?

• It doubles

• It triples

• It remains the same

• It halves

In a 1 to 5 dilution, what does the '5' represent?

• The volume of the solvent added

• The total volume of the diluted solution

• The volume of the stock solution

• The concentration of the solute

What is the dilution factor for a 1 to 10 dilution?

• 1

• 15

• 5

• 10

Which of the following is a correct way to make a 1 to 5 dilution?

• Add 5 ml of solution to 5 ml of water

• Add 1 ml of solution to 4 ml of water

• Add 4 ml of solution to 1 ml of water

• Add 1 ml of solution to 1 ml of water

What is another term for a 1 to 5 dilution?

• 5-step dilution

• 5-phase dilution

• 5-fold dilution

• 5-part dilution
