GEOMETRY Molecular geometry is the three-dimensional arrangement of the atoms that constitute a molecule. It determines several properties of a substance including its reactivity‚ polarity‚ phase of matter‚ color‚ magnetism‚ and biological activity.[1][2] The angles between bonds that an atom forms depend only weakly on the rest of molecule‚ i.e. they can be understood as approximately local and hence transferable properties. The specific three dimensional arrangement of atoms in molecules is referred

CHEM 301 LECTURE Unit 1 0 . COORDINATION CHEMISTRY Factors t hat affect solubility: Common ion: decrease in solubility Complex ion: increase in solubility How does complex ion formation increase solubility? Consider the complex ion formation between silver and ammonia: + Ag + 2NH3 A g(NH3 )2 + Kf = 1 .5 x 10 7 where Kf i s the formation constant (always >1 ‚ formation of the complex is highly favorable) Complex ion formation increases the solubility of sol ids in water
