Chapter 3

Question 1

Solution

Answer 1

A homogenous mixture

Question 2

Solute

Answer 2

Portion of solution in lesser quantity

Question 3

Solvent

Answer 3

Portion of solution in greater quantity

Question 4

Soluble

Answer 4

Maximum [] is greater then or equal to 0.1M 25 degrees

Question 5

Low solubility

Answer 5

Max concentration is less then 0.1M @ 25 degrees

Question 6

Solubility

Answer 6

The maximum amount of solute that can go into a given volume of solvent at a specific temp

Question 7

Saturated solution

Answer 7

• At solubility
• Solid present
• Rates are equal (rate of ionization = rate of crystallization)

Question 8

Iconic solutions

Answer 8

Formed by compounds that will dissociate into ions (to some degree)
-ionic compounds
       ~metal - nonmetal (any anion)
       ~ammonium-nonmetal
       ~acids

Question 9

Molecular solutions

Answer 9

No ions

Ex. C6H12O6 s—> C6H12O6 am

Question 10

Ksp

Answer 10

Solubility product constant or ion product constant
Describes a saturated solution equilibrium

Describes the max []s of ions that can be in solution together

Question 11

Predicting if a precipitate will form

Answer 11

Trail ksp < ksp ~> no ppt - below solubility

Trail ksp = ksp ~> no ppt-@ solubility

Trail ksp > ksp. ~> ppt - saturated solution
