Study Notes

Gas Solubility

According to Henry's law, the mass of a gas dissolved in a solvent is directly proportional to the partial pressure of the gas above the solvent.

Solution Concentration

In a saturated solution, the concentration of solute depends primarily on the temperature.

Chemical Reactions

The reaction quotient (Q) measures the ratio of product concentrations to reactant concentrations at any time during a chemical reaction.

Electrolytes

Strong electrolytes dissociate completely into ions in an aqueous solution.

Buffer Solutions

A buffer solution is a solution that resists changes in pH when an acid or base is added.

Solution Saturation

A solution is said to be unsaturated if it can still dissolve more solute.

Equilibria

According to the characteristics of equilibria involving physical processes, the temperature remains constant during dissolution of gases in liquids.

Phase Equilibrium

Solid-to-liquid equilibrium occurs at the melting point of a substance.
Dynamic equilibrium is the stage of the solution where the rates of dissolution and crystallization are equal.

Physical Equilibrium

Equilibrium between two different physical states means that the rates of forward and reverse physical processes are equal.
Dynamic equilibrium means that the rates of forward and reverse reactions are equal, but not zero.

Buffer Solution pH

Dilution with water does not affect the pH of a buffer solution.

Boiling Point

The boiling point of a liquid depends on the intermolecular forces between its molecules.

Dynamic Equilibrium

In dynamic equilibrium, the concentrations of reactants and products do not change over time, but the rates of forward and reverse reactions are equal.
