Properties of Solutions

Question 1

what is a solution?

Answer 1

consists of a solute dissolved into a solvent

Question 2

what do we often use to describe solutions?

Answer 2

concentration

Question 3

what happens to the density of a solution as it becommes more concentrated?

Answer 3

it starts to become very different from pure water and thus the volume of the solution and the mass of solution are not numerically equal

Question 4

does a solute usually all dissolve into a solution?

Answer 4

no, the solute often has limited solubility in a solvent

Question 5

a solution that contains the maximum amount of solute that can be dissolved is called a…

Answer 5

saturated solution

Question 6

what are the three outcomes that are needed for a solute to dissolve into a solvent?

Answer 6

1. requires energy to overcome the solute-solute bonds
2. requires energy to overcome the solvent-solvent bonds
3. produces energy from the formation of solute-solvent attractions

Question 7

what is vapor pressure?

Answer 7

it is an equilbrium pressure. its the partial pressure at which the rate of condensation equals the rate of evaporation regarding a substance.

Question 8

what is the definition of the normal boiling point of a liquid and how does this change will atlitude?

Answer 8

the temperature at which the vapor pressure equals the atmospheric pressure at a particular altitude. boiling point will decrease with increasing altitude and increase vice versa

Question 9

What is the equaiton assosciated with Rauolts law?

Answer 9

the vapor pressure of a soluton = mole fraction of the solute x vapour pressure of solvent
