Science > Chemistry > Chemical Equilibrium > Gibb’s Energy and Chemical Equilibrium Gibb’s Energy or Free Energy: Gibb’s energy or free energy is a thermodynamic function which helps us in the development of a criterion of spontaneity or feasibility of a process. It refers to the capacity of the system to do useful work. Gibb’s […]

Solubility Product

Science > Chemistry > Physical Chemistry > Ionic Equilibria > Solubility Product In this article, we shall study the concept of solubility, solubility product, and its applications. Some ionic solids are highly soluble in water while others are almost insoluble in it. The solubility of ionic solid depends on lattice enthalpy of the salt and […]

Common Ion Effect

Science > Chemistry > Physical Chemistry > Ionic Equilibria > Common Ion Effect In this article, we shall study the common ion effect and its applications. The phenomenon in which the degree of dissociation of any weak electrolyte is suppressed by adding a small amount of strong electrolyte containing a common ion is called a […]

Buffer Solutions

Science > Chemistry > Physical Chemistry > Ionic Equilibria >Buffer Solutions In this article, we shall study the concept of buffer solution, its characteristics, its types, and preparations. Buffer Solution: A solution, which resists the change in its pH value, even on the addition of a small amount of strong acid or base is called […]

Ionic Product of water

Science > Chemistry > Physical Chemistry > Ionic Equilibria > Ionic Product of water In this article, we shall study concepts of the ionic product of water, pH and pOH of a solution and their importance. Ion Equilibrium in Water: Water has electrical conductivity, hence it must undergo dissociation. “Dissociation of pure water to a […]

Ostwald’s Dilution Law

Science > Chemistry > Physical Chemistry > Ionic Equilibria > Ostwald’s Dilution Law In this article, we shall study the Ostwald’s dilution law and its application to weak electrolytes, like weak acids and weak bases. Ostwald’s Dilution Law: A mathematical expression of the law of mass actions that gives the relationship between equilibrium constant/dissociation constant, […]

Ionic Theory

Science > Chemistry > Physical Chemistry > Ionic Equilibria > Ionic Theory In this article, we shall study Arrhenius ionic theory, the concept of ionization and dissociation, Applying law of mass action to reactions involving ions. Electrolytes on the Basis of Ionic Theory: According to Arrhenius ionic theory, a substance (acid) base or salt, which […]
