Equilibrium, Acids & Bases Unit Test Vocab

Homogenous Equilibrium

All the reactants and products are in the same physical state

Heterogeneous Equilibrium

When the reactants and products are present in more than one physical state

Law of Chemical Equilibrium

States that a given temperature, a chemical system might reach a state in which a particular ratio of reactant and product concentrations has a constant value

Reversible Reaction

A chemical reaction that can occur in both the forward and reverse direction

Common Ion Effect

Lowering the solubility of a substance because of the presence of a common ion

Titrant

A burst is filled with the titrating solution of known concentration. Also known as the standard solution

Titration

A method for determining the concentration of a solution by reacting a known volume of that solution with a solution of known concentration

Neutralizing Reaction

A reaction in which an acid and a base in an aqueous solution react to produce a salt and water

End Point

The point at which the indicator used in a titration changes color

Equivalence Point

The point at which moles of the H+ ion from the acid equal moles of the OH- ion from the base

Acid-base Indicator

Chemical dyes whose colors are affected by acidic and basic solutions

Dilution Equation

M1 x V1 = M2 x V2
