LT#9: Ksp Calculations & Predicting Pecipitates Flashcards
1
Q
Define Solubility
A
The amount of solute that will dissolve in a specific amount of solvent at a certain temperature.
2
Q
How do you write a solubility equilibrium chemical equation?
A
Write the solid as the reactants and break it apart into its separate dissolved ion.
3
Q
How is solubility and Ksp related?
A
The higher the Ksp the more favoured the forward reaction and the higher the compound’s solubility.
4
Q
How are Ksp and Kc calculations different?
A
Ksp expressions only have the [products] raised to their coefficients since the reactant is a pure solid (and its concentration doesn’t change).
The solubility tells you you the equilibrium concentration so no ICE Tables are needed.
