IPC Unit 5 Lesson 2

Frieda makes a solution that contains 5.7 g of KCl dissolved in 200 g of water. What would be your percent by mass of KCl in the water solution?

2.8%

Jason has a 75% solution of rubbing alcohol in 100 mL of solution. How many mL of rubbing alcohol are in this solution?

75 mL

Which solution is the most concentrated? - 3% Hydrogen Peroxide - 6% Hydrogen Peroxide - 9% Hydrogen Peroxide

9% Hydrogen Peroxide

a solution in which added solute particles are completely dissolved

Unsaturated Solution

Which statement is true?

Both the more concentrated a solution is with a solute, the more solute is dissolved in the solution AND the more concentrated a solution is with a solute, the more the solution will have the properties of the solute.

a measured value that expresses how much of a solute dissolves in a certain amount of solvent

Concentration

a substance that is unable to dissolve in another substance

Insoluble

Jon added blue food coloring to a glass of water. Adding one drop resulted in a light blue color, and adding 5 drops resulted in a dark blue color. Looking at the intensity of color in a solution is one way to describe a solution's concentration ___.

Qualitatively

a solution that retains the maximum amount of solute it can hold at a given temperature

Saturated Solution

a substance capable of dissolving in a certain amount of solvent

Soluble

a solution that contains more solutes than a saturated solution when the temperature is the same

Supersaturated Solution

_____Which two factors can create supersaturated solutions?

both increase in pressure and temperature
