Tags and Description

31 Terms

1

Soluble

Capable of being dissolved

New cards
2

Solute

Substance that dissolves into a solvent

New cards
3

Solvent

Substances that act as the dissolving medium to dissolve the solute

New cards
4

Tyndall Effect

The passage of light through a mixture

New cards
5

Electrolyte

An Ionic compound that dissolves in water and conducts an electric current

New cards
6

Nonelectrolyte

A Covalent compound that dissolves in water and does not conduct an electric current

New cards
7

Solution

Light passes straight/directly through

New cards
8

Suspension

No light passes through

New cards
9

Colloid

Light is scattered

New cards
10

3 Factors that affect the Rate of Dissociation/Dilution

  1. Stir/mix/agitate

  2. Add heat

  3. Increase surface area

New cards
11

Unsaturated Solution

Adding any amount of solute (under the maximum solvent)

New cards
12

Saturated Solvent

Adding the maximum amount of solute to the solvent

New cards
13

Supersaturated Solution

Adding the maximum amount of solute to the solvent (with heat)

New cards
14

Solubility

Any substance in any phase that will dissolve in another substance in any phase

New cards
15

Hydration

A compound that has the ability to attach waters to its molecular structure

New cards
16

Immiscible

Liquids that will not dissolve in one another

New cards
17

Miscible

Liquids that will dissolve in one another

New cards
18

Henry’s Law

The solubility of a gas in a liquid is proportional to the partial pressure of the gas on its surface

New cards
19

Effervescence

The rapid release of a gas from a liquid

New cards
20

Rule of Thumb

Like dissolves like (nonpolar dissolves nonpolar, polar dissolves polar)

New cards
21

KNOW THIS

A solute dissolves in a solvent to form a solution

New cards
22

Which mixture has the LARGEST particles?

Suspension

New cards
23

What are the 3 parts that make an electrolyte and what is an example?

Ionic, dissolves in water, electric current, Gatorade

New cards
24

Which will effervesce more: a warm bottle of sprite or a cold bottle of sprite? Why?

warm bottle, the particles are moving faster and the gas particles are released faster

New cards
25

Concentration

the amount of solute in a solution or solvent

New cards
26

Molarity (M)

moles of solute/liters of solution (n/L) or mass of solute/MM of solute/liters of solute (m/MM/L)

New cards
27

Molality (m)

moles of solute/kilograms of solvent (n/Kg) or mass of solute/MM of solute/kilograms of solvent (m/MM/Kg)

New cards
28

What are the 3 parts to a non-electrolyte? What is an example?

Covalent compound, dissolves, cannot conduct electricity, sugar water

New cards
29

What does the Tyndall Effect do to a solution?

light goes through it and you can see it

New cards
30

What does the Tyndall Effect do to a colloid

light is scattered

New cards
31

What does the Tyndall Effect do to a suspension

light cannot pass through it
