Chapter 18

Question 1

Ksp

Answer 1

DOES NOT INCLUDE SOLIDS AND LIQUIDS

Question 2

Finding molar solubility

Answer 2

1. write out the equation
2. make ICE box with the initial concentration. the change should be +/- S (if it has stoichiometry multiply S by it)
3. plug into Ksp
4. solve for S

Question 3

Finding concentration that is remaining

Answer 3

1. Write our equation
2. for the initial of reactants, (Volume)(Concentration)/ (Total volume); these go into the I part
3. subtract by least amount
4. the subtract amount for the wanted is x
5. plug into Kf
6. solve for x

Question 4

Q < Ksp

Answer 4

solution is unsaturated and more of the solid will dissolve

Question 5

Q > Ksp

Answer 5

solution is supersaturated. the excess solid precipitates out
