Guiding questions for Model 105: Solubility, Solubility Product and Ksp

399.In what way are the definitions "soluble" and "insoluble" we used in the first semester exaggerations?

400.Now that I know about dynamic equilibrium, can I articulate a more accurate interpretation of the chapter 4 solubility "rules"?

401.What assumption am I making about the solvent?

402.How can I tell which of two salts is more soluble in water?

403.What does "solubility" mean?

404.What does "solubility product" mean? (hint: here, 'product' should be interpreted as the result of multiplication, rather than the result of a chemical reaction).

405.When writing the expression for a solubility product, why do I not include reactant concentration in the denominator?

Guiding questions for Model 106: Ksp and Solubility Calculations of a Salt in Pure Water

406.How can I apply RICE-table strategies to solve problems involving semi-soluble salts?

a.How do I calculate Ksp from solubility?

b.How do I calculate solubility from Ksp?

407.Why are there no entries under the solid reactant in either example?

408.How is calculating solubilty given Ksp like a limiting reagent problem?

409.When should I use a co-efficient as an exponent?

410.When should I multiply a concentration by a co-efficient? Why should I not multiply a concentration by a co-efficient?

Guiding questions for Model 107: Common Ion Effect

411.What is meant by "common ion"?

412.What is the "Common Ion Effect"?

413.Does the common ion effect make sense in light of Le Châtelier's principle?

414.Do I expect the presence of a common ion to raise, or lower, the solubility of any particular salt?

415.How does the small-x approximation help me solve problems involving calculating solubility in the presence of a common ion?
