Explain the meaning of the following words :
Volatility is a property of substance to vaporize. Since high volatile compounds have weak intermolecular interaction, they exhibit high vapor pressure and low boiling point. Reducing nature is a characteristic of element to lose an electron upon interaction with another atom. Acidic nature or acidity is a characteristic of compound, which shows a tendency to produce proton upon dissolving of substance. For organic and mineral acids, acidity can be estimated by using value of dissociation constant for R-H bond. Thermal stability is the stability of molecules upon heating. Compounds having low thermal stability are decomposed at low temperature, and substances with high thermal stability are stable upon heating and they can be sublimated or distillated.
