Concentration and Solubility Pt. 1

Question 1

What is the solvent?

Answer 1

The thing that does the dissolving

Ex. water

Question 2

what is the order when writing a solution?

Answer 2

solute then solvent

Question 3

solute-solvent examples

Answer 3

gas-liquid
gas-gas
liquid-liquid
liquid-solid
solid-liquid
solid-solid

Question 4

Tyndall Effect

Answer 4

light is scattered and dispersed into a transparent medium. a laser can’t be seen in a clear solution.

Question 5

what are the two types of solutions

Answer 5

electrolyte and nonelectrolyte

Question 6

what is a electrolyte

Answer 6

a substance that dissolves in water to give a solution that conducts electric current

ionic

Question 7

what is a nonelectrolyte

Answer 7

a substance that dissolves in water to give a solution but doesn’t conduct an electric current

covalent

Question 8

what are the two types of electrolytes

Answer 8

strong and weak

Question 9

what makes up a strong electrolyte

Answer 9

• conducts electricity well
• all ions are dissolved

Question 10

what makes up a weak electrolyte

Answer 10

• conducts electricity poorly
• small amount of ions are dissolved

Question 11

what are the three things that can affect the rate of dissolutions

Answer 11

1. increase surface area of solute
2. agitate solution
3. heat solution

Question 12

what is a saturated solution

Answer 12

a solution that contains the max. amount of dissolved ions

Question 13

what is a unsaturated solution

Answer 13

a solution that contains less solute than the max amount

more solute can be added

Question 14

what is a supersaturated solution

Answer 14

a solution that contains more solute than a saturated solution DUE TO ADDING HEAT

Question 15

“like Dissolves like” depends on what three things

Answer 15

1. type of bonding
2. polarity vs. nonpolarity
3. IMF’s (intermolecular forces)

Question 16

how do you identify a hydrate

Answer 16

when the solution has water as the solvent and ionic crystals with H2O at the end of the formula

Question 17

what does immiscible mean

Answer 17

liquids that aren’t soluble in each other

Ex. Water and Oil

Question 18

what does Miscible mean

Answer 18

Liquids that dissolve freely in each other

Ex. alcohol and water

Question 19

What happens when the pressure is increased in a Gas-Liquid Dissolution

Answer 19

it increases the Gas solubility

Question 20

what happens when the temperature is increases in a gas-liquid dissolution

Answer 20

it decreases the Gas solubility

Question 21

is the solubility of Gas in a liquid directly or indirectly proportional to the pressure of gas on the surface of the liquid

Answer 21

directly

Question 22

what is effervescence

Answer 22

the rapid release of a gas from a liquid that the gas is dissolved in

Ex. when bubbles and foam form from soda

Question 23

what does it mean for a solution to be concentrated and not dilute

Answer 23

it has a large amount of solute

Question 24

what does it mean for a solution to be dilute instead of concentrated

Answer 24

it has a small amount of solvent

Question 25

what is molarity

Answer 25

the number of moles of solute in 1 Liter of solution

you must know the molar mass in order to find the molarity

Question 26

what is molarity

Answer 26

the concentration of a solution in moles of solute per kg of solvent
