... Titration is an important technique in volumetric analysis. It involves adding an exact amount of one reactant (called titrant) from a buret to another reactant (called analyte) in a flask or beaker. The primary objective of titration is to determine the molar concentration of one solution (may be t ...

Chemical equilibrium
In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time. Usually, this state results when the forward reaction proceeds at the same rate as the reverse reaction. The reaction rates of the forward and backward reactions are generally not zero, but equal. Thus, there are no net changes in the concentrations of the reactant(s) and product(s). Such a state is known as dynamic equilibrium.
