Solubility Product Constant (Ksp): This is similar to Qsp but specifically refers to equilibrium conditions – when no more solute will dissolve into solution. It’s like checking your bank balance right after payday – before any bills are paid or purchases made.
Reaction Quotient (Q): This term describes the state of a reaction at any point in time. It's like taking a snapshot of your bank account at any random moment.
Equilibrium Constant (K): This is the ratio of concentrations when the forward and reverse reactions occur at the same rate. It’s like balancing your checkbook – income equals expenses, so there’s no net change.
