Chem Lesson 6: 15.1 - 15.2

Question 1

Solubility

Answer 1

Ability of a solute to dissolve in a solution

Question 2

Solubility Rules and Exceptions

Answer 2

N nitrates
A acetates
G group 1

S sulfates
A ammonium (nh4+)
G group 17

Execemptions
1. Never soluble with sulfates or group 17
P Lead (Pb)
M Mercury (Hg2+2)
S Silver (Ag+)

Castro Bear
2. Never soluble with sulfates
Ca2+ Sr 2+ Ba 2+

Most Carbonates are insoluble: Exceptions Group 1 and NH4+

Most Phosphates are insoluble - Exceptions Group 1 and NH4+

Question 3

Ksp Constant (Equilibrium)

(Solubility Product)

Answer 3

Level at which a solute dissolves in a solution.

Plug concentrations into ksp to solve.

(Reactants aren’t in Ksp)

Question 4

Molar Solubility

Answer 4

The number of moles of the solute that dissolves to form a liter of saturated solution

Question 5

Another name for Solubility Product

Answer 5

Ksp

Question 6

Precipitation Reaction

Answer 6

When to ions react in a solution to form a insoluble compound

Question 7

Qsp < Ksp (will precipitate form)

Answer 7

No because there’s more reactants than products.

Question 8

Qsp > Ksp (will precipitate form)

Answer 8

Yes because there’s more products than reactants.

Question 9

Electrolyte

Answer 9

Substance that gives ions when dissolved in water.

Question 10

Another name for Solubility Product

Answer 10

Ksp

Question 11

Calculate Molar Solubility (solve for what?)

Answer 11

Solve for x

Question 12

What physical state must an ionic compound have for Ksp

Answer 12

Solid (s)

Question 13

Unit for Mass

Answer 13

Grams

Question 14

Mass to mole

Answer 14

Mole = Mass * L

Question 15

When to use ICE table

Answer 15

When you’re not a saturation (equilibrium)

Question 16

Which one will precipitate first? Ksp that’s lower or higher?

Answer 16

Lower
