solubility equilibria Flashcards
What is solubility and what is its unit?
amount of solute dissolved in g/L
What is molar solubility and what is its unit?
amount of solute dissolved in mol/L (M)
How do you find molar solubility on an ICE table?
Molar solubility is equal to x in the C row of and ICE table
What is Ksp and its formula?
Equilibrium constant for dissolution of solid salt, does not include reactants because they are solid
How does pH affect solubility?
The higher the pH, the lower the solubility
What is precipitation and when does it occur?
When solid forms from aqueous solution, occurs when Q > Ksp
How does the common ion effect affect solubility?
When common ions are added, solubility equilibrium shifts left
What is an amphoteric hydroxide?
A metal hydroxide that reacts with both acids and bases
What is a complex ion?
A cation + metal ion with a lewis base
How does formation of complex ions affect solubility?
Formation of complex ions increases solubility of salts with common ion
What is a ligand?
A lewis base that binds to metals to form complex ions
What is Kf
The equilibrium constant to form one mole of a complex ion
What is Kd?
The equilibrium constant to dissociate one mole of a complex ion
