The rapid change of pH near the stoichiometric point of an acid-base titration is the basis of indicator detection. pH of the solution is related to ratio of the concentrations of the conjugate acid (HIn) and base \[(I{{n}^{-}})\]forms of the indicator by the expression [CBSE PMT 2004]

\[\log \frac{[I{{n}^{-}}]}{[HIn]}=p{{K}_{In}}-pH\]

\[\log \frac{[HIn]}{[I{{n}^{-}}]}=pH-p{{K}_{In}}\]

\[\log \frac{[I{{n}^{-}}]}{[HIn]}=pH-p{{K}_{In}}\]

\[\log \frac{[HIn]}{[I{{n}^{-}}]}=p{{K}_{In}}-pH\]

DIRECTION: Read the passage given below and answer the questions that follows: In hexagonal systems of crystals, a frequently encountered arrangement of atoms is described as a hexagonal prism. Here, the top and bottom of the cell are regular hexagons and three atoms sandwiched in between them. A space-of this model of this structure, called hexagonal close-packed (HCP), is constituted of a sphere on a flat surface surrounded in the same plane by six identical spheres as closely as possible. There spheres are then placed over the first layer so that they touch each other and represent the second layer. Each one of these three spheres touches three spheres of the bottom layer. Finally, the second layer is covered with third layer that is identical to the bottom layer in relative position. Assume radius of every sphere to be 'r'. The number of atoms in the HCP unit cell is
