solubility

Question 1

A property that depends only upon the number of solute particles, and not upon their identity.

Answer 1

Colligative property

Question 2

Freezing-point

Answer 2

depression - when a nonvolatile solute is added, the freezing point decreases

Question 3

Boiling-point

Answer 3

elevation - when a nonvolatile solute is added, the boiling point increases

Question 4

Vapor-pressure

Answer 4

lowering - when a nonvolatile solute is added, the vapor pressure decreases (which leads to higher boiling points)

Question 5

vapor prressure info

Answer 5

The molecules in a liquid are held together by relatively weak forces.
In any sample of a liquid, some of the particles at the surface have sufficient energy to escape from neighboring molecules and enter the gas phase.
As the temperature of a liquid increases, the particles have more energy and more particles escape from the surface.

Question 6

When a substance, which is normally a solid or liquid at room temperature, enters the gas phase

Answer 6

vapor

Question 7

vapor particles exert pressure in the gaseous phase. The pressure that a vapor exerts is known as vapor pressure.

Answer 7

vapor pressure

Question 8

boiling point

Answer 8

The temperature at which the vapor pressure of the liquid is 101.3 kPa, which is standard atmospheric pressure

Question 9

heat of vaporization

Answer 9

the heat required to change 1 mol of a substance from a liquid AT ITS BOILING POINT to 1 mol of vapor.

Question 10

molecular

Answer 10

When one mole of sugar, which is a molecular substance, is dissolved in water, one mole of particles is produced in solution. One mole of particles lowers the freezing point of 1000 g of water by 1.86𝆩C. (less than ionic because less # of moles dumbass)

Question 11

ionic

Answer 11

When one mole of sodium chloride, which is an ionic substance, is dissolved in water, two moles of particles are produced in solution. Two moles of particles lowers the freezing point of 1000 g of water by 3.72𝆩C.

Question 12

The substance that is being dissolved and present in the smaller amount (can be solid, liquid or gas). It is possible to have more than one solute.

Answer 12

solute

Question 13

The substance that dissolves the solute and present in the greater amount (can be solid, liquid or gas). There is only one solvent. Water is the most common solvent. (Solutions in water are called aqueous solutions (aq))

Answer 13

solvent

Question 14

A homogeneous mixture of substances in the same physical state

Answer 14

solution

Question 15

It is a homogeneous mixture.
The size of solute particles in the solutions is extremely small. …
The particles of a solution cannot be seen even with a microscope.
The particles of a solution pass through the filter paper. …
It is very stable.

Answer 15

characteristics of a solution

Question 16

concentrated vs diluted solution

Answer 16

The term “dilute solution” refers to a solution in which a small amount of solute is dissolved in a large amount of solvent. The term “concentrated solution” refers to a solution in which the amount of solute dissolved is more compared to the amount of solvent.
