Thermodynamics
Consider an ionic solid that dissolves in water according to the equation:
The equilibrium constant for the reaction,
is defined as the solubility product of MnXm. The form of this equilibrium is important in understanding effects such as the influence of complexion and pH and also the common ion effect: it may be seen that adding one of the ions Mm+ or Xn- will shift Reaction 1 to the left and so less the solubility of the salt. Thus AgCl(s) is much less soluble in a solution containing 1 M Ag+ (e.g. from soluble AgNO3) than otherwise.
What do you understand by Miller indices of a crystal plane? Miller Indices are a symbolic vector representation for the orientation of an atomic plane in a crystal lattice an
Q. What are the Chemical Properties of Nitric Acid? Ans. Reactions as an acid: Nitric acid ionizes well because it is a strong acid. HNO 3 --> H + + NO3 - It tur

The Bohr orbit radius for the hydrogen atom (n=1) is approximately 0.530 Å . The radius for the first excited state (n=2) orbit is: (1) 0.13Å
Delocalisation of electrons in conjugated system is called resonance. For example there is delocalisation of electrons in benzene ,hence we write kekule structure for benzen.
