Solutions

Question 1

Solution

Answer 1

Homogenous mixture

Question 2

Solute

Answer 2

Substance being dissolved

Question 3

Solvent

Answer 3

Present in greater amount, in what solute is being dissolved

Question 4

Molarity

Answer 4

A way to describe concentration of a solution used in the lab
Number of moles dissolved in each liter of solution

Question 5

Molarity formula

Answer 5

Moles/ liters
M= n/L
M=n/v
N=MV

Answer 10

Need to be enough energy

Question 11

How does dissolving happen with characteristic of solute and solvent (polarity)

Answer 11

Like dissolved like

Except ionic dissolved in polar

Question 12

Seeding

Answer 12

Putting crystal in

Question 13

Unsaturated

Answer 13

More solute dissolves

Crystal will dissolve

Question 14

Saturated

Answer 14

No more solute dissolves

Crystal falls to the bottom

Question 15

Super saturated

Answer 15

Becomes unstable
Crystal forms
Crystal will fall with more than it had put in

Question 16

What is the relationship with concentration from unsaturated to saturated

Answer 16

Increases

Question 17

Stronger solvent when add

Answer 17

Heat energy

Question 18

Solubility

Answer 18

Maximum grams of solute that will dissolve in 100g of solvent at given temp

Question 19

Solubility curve

Answer 19

Shows the dependence of solubility on temperature

Question 20

Solubility curves
Below
On line

Answer 20

Below- unsaturated

On line- saturated

Question 21

On solubility curve Over line is

Answer 21

Supersaturated if

Put it in saturated with some on bottom, if heated up and dissolve and cooled down then supersaturated

Answer 22

Low temps 
High pressure (Henry law) a

Question 23

Solids solubility

Answer 23

Solids are more solvable at high temps

Question 24

Colligative property

Answer 24

Property that depends on the concentration of the solute particles, not their identity

Question 25

Freezing point

Answer 25

Freezing point of a SOLUTION

is lower than freezing point of a PURE SOLVENT

Question 26

Boiling point

Answer 26

Boiling point of a SOLUTION is higher than the boiling point of the PURE SOLVENT

Question 27

Vapor pressure

Answer 27

vapor pressure of a SOLUTION is lower than the vapor pressure of PURE SOLVENT

Question 28

Osmotic pressure

Answer 28

Osmotic pressure of a SOLVENT is higher than the osmotic pressure of a PURE SOLVENT

Question 29

What happens when impurities are introduced to a solution

Answer 29

They disturb the stability intermolecular bonds between solvent molecules

Question 30

Osmosis

Answer 30

The movement of water across a semi permeable membrane at first the concentration of the solute is very high on the left but overtime the water moves across the semipermeable membrane and dilutes the particles
