Unit 7: Equilibrium

Ksp

________ is solubility product constant, which has no denominator because reactants are solids.

Law of Mass Action

The ________ is the equilibrium expression that determines the relationship between reactant and product concentrations.

Kc

________ is constant for molar concentrations.

Q

reaction quotient

Le Chatelier’s Principle

When a stress is added to a reaction, the equation will change to adjust for the stress and revert back to equilibrium.

not shift

Ka

________ is the acid dissociation constant.

concentration and pressure

When ________ is changed, the equilibrium constant will eventually revert to the original value

equilibrium reactions

In ________, the reaction is reversible, where the reactants from products and then go back to reactants constantly.

Ksp

________ is the measurement of how much a salt dissolves in a solution.

Common Ion Effect

When an element is added to a solution with a salt, the salt equilibrium will change if the element is similar.
