Web28 mrt. 2013 · Moreover, if the solubility of an API and its CF are known, the solubility of a CC can be calculated directly: (10) K CC s = K API s ∗ K CF s ∗ e Δ G / RT Very often, pharmaceutically acceptable CFs are stored in specific libraries and their physico-chemical characteristics are known. In this case, Eq. 8 will allow the quick estimation of the relative … WebLattice Energies and the Strength of the Ionic Bond . The force of attraction between oppositely charged particles is directly proportional to the product of the charges on the two objects (q 1 and q 2) and inversely proportional to the square of the distance between the objects (r 2).The strength of the bond between the ions of opposite charge in an ionic …

The lattice energy of nearly any ionic solid can be calculated rather accurately using a modified form of Equation 4.1: (4.2.1) U = − k ′ Q 1 Q 2 r 0, w h e r e U > 0. U, which is always a positive number, represents the amount of energy required to dissociate 1 mol of an ionic solid into the gaseous ions. dr. garfield johnson houston
