What is a Solution?
What is the definition of a solution?
A homogeneous mixture of two or more substances.
In saltwater, what is the solute?
Salt
What type of solution is air?
Gas Solution
What happens to the rate of dissolution when you stir a solution?
It Increases
What is the difference between a dilute and a concentrated solution?
A dilute solution has a small amount of solute compared to the solvent, while a concentrated solution has a large amount of solute.
True or False? In a solution, the solute and solvent can be separated easily by filtration.
False
What is the solvent in a sugar-water solution?
Water
Is bronze an example of a solid, liquid, or gas solution?
Solid Solution
How does temperature affect the rate at which sugar dissolves in water?
Higher temperatures increase the rate of dissolution.
How can you make a solution more concentrated?
Add more solute or evaporate some solvent.
What is an example of a common liquid solution?
Saltwater, sugar in tea
Which component of a solution is usually present in the greatest amount?
Solvent
What do we call a solution where water is the solvent?
Aqueous solution
Which dissolves faster: granulated sugar or a sugar cube?
Granulated sugar.
What is a real-life example of concentration in cooking?
Adding more sugar to make syrup.
How is a solution different from a suspension?
In a solution, particles are fully dissolved and don’t settle out, while in a suspension, particles are larger and may settle over time.
If you dissolve 10 grams of salt in 100 grams of water, what is the solvent?
Water
Name a solid solution used in everyday life.
Steel, bronze, or brass.
What effect does crushing a solute have on its dissolution rate?
Crushing increases the rate because it increases the surface area.
How would you dilute a solution of lemonade that is too strong?
Add More Water
What happens to the solute in a solution?
It dissolves completely and spreads uniformly throughout the solvent.
True or False: A solvent can only be a liquid.
False.
Solvents can be solids, liquids, or gases.
True or False: All solutions are liquids.
False
Why does powdered sugar dissolve faster than a sugar cube?
Because it has a larger surface area in contact with the solvent.
What does it mean if a solution is saturated?
It has the maximum amount of solute dissolved in it, and no more can dissolve at that temperature.
