How Soap perform cleansing action?
Soaps and detergents perform the cleaning action because the polar parts of their molecules are water soluble due to hydrogen-bonding and non-polar parts remain outside water.

What is chromatography?
The word chromatography originates from the Greek word ‘khromatos’ meaning color writing. Definition: A technique used for separating the components of a mixture by their distribution between a stationary and a mobile phase is called chromatography. Chromatography Principle: Chromatography is a method used primarily for the separation of a sample mixture and involves the distribution…
Relationship between Boiling Point and External Pressure
Greater the pressure exerted on the liquid, greater would be the boiling point or vice versa. Boiling point of a liquid can be increased by increasing the external pressure on the liquid, whereas it can be decreased by decreasing the external pressure on the liquid. At 1 atmospheric pressure water boils at 100°C. At high…
How do Hydrogen Bonding Affect Solubility?
In addition to water, ethyl alcohol (C2H5OH) also has the tendency to form hydrogen bonds. So, ethyl alcohol can dissolve in water because both can form hydrogen bonds with each other. Similarly, carboxylic acids are also soluble in water, if their sizes are small. Hydrocarbons being non-polar are not soluble in water at all, and…
Dipole Dipole Forces Definition
The attractive forces between the positive end of one molecule with the negative end of other molecule are called dipole-dipole forces. Explanation: In case of HCl, There is much electronegativity difference between hydrogen and chlorine. Due to this chlorine being more electronegative develops a partial negative charge whereas hydrogen develops partial positive charge. Hence the…
What is Evaporation?
Definition: The spontaneous escaping of molecules of a liquid from their surface at any temperature is called evaporation. Evaporation Process: Most common question in this regard is, How does evaporation work? All the liquid molecules do not contain the same kinetic energies. Speed of molecules depends upon kinetic energy. Molecules with high kinetic energy move…
Energetics of Phase Changes
Whenever matter undergoes a physical or’ a chemical change, it is always accompanied by an energy change in the form of heat. This change in energy is the quantitative measure of the difference in the strength of intermolecular forces. In case of physical change at constant pressure called enthalpy change. Enthalpy change is of three…
