A ratio that measures how much solute can dissolve in a solvent at a given temperature.

• Reversible Reaction

• Single-Displacement Reaction

• Solubility Product Constant

• Solubility

The product of the molar concentrations of dissociated ions in a saturated solution, where each icon is raised to the power of its stoichiometric coefficient. Denoted Ksp

• Solubility Product Constant

• Resonance Structures

• Single-Displacement Reaction

• Reversible Reaction

A chemical reaction in which an atom or ion of one compound is replaced by another atom or ion (such as A+BC > B+AC).

• Reversible Reaction

• Resonance Structures

• Single-Displacement Reaction

• Reduction Potential

A process that will proceed bidirectionally to form both product and reactant.

• Reversible Reaction

• Reduction Potential

• Reduction

• Resonance Structures

Alternate Lewis structures of the same molecule that show the delocalization of electrons within that molecule; Lewis structures that contribute to a resonance-stabilized system. Resonance structures have the same atomic connectivity but differ in the distribution of electrons.

• Reduction Potential

• Reduction

A measure of the tendency of a species to be reduced, commonly used in identifying the anode and cathode of an electrochemical cell.

• Reduction

• Reducing Agent

• Reaction Rate

• Reduction Potential

A reaction in which a species gains electrons.

• Reduction

• Reaction Quotient

• Reducing Agent

• Reaction Rate

A species that is oxidized in the process of reducing another species.

• Reaction Quotient

• Reducing Agent

• Reaction Rate

The measure of how quickly reactants are consumed and products are formed, commonly expressed in terms of mol L-1 S-1.

• Reaction Order

• Reaction Rate

• Reaction Mechanism

• Reaction Quotient

The ratio of the concentrations of the products to the concentrations of the reactants at any point during a reaction, where each reactant and product in the expression is raised to the power of its stoichiometric coefficient. Commonly denoted by Q. Usually compared to the equilibrium constant to determine the direction a reaction will proceed to regain equilibrium.
