Document Summary
What a soluion is composed of: a soluion is composed of a solute and a solvent. What causes and how do molecules in a soluion to interact: governed by coulomb"s law. Coulomb"s law: the force of atracion or repulsion between two point changes is directly proporional to the product of the two charges and inversely proporional to the square of the distance between them: f=kqq"/r2. Atracion or repulsion if: q=-q" : diferent charge so atracion. Structure of charges in phases: ions, dipoles, non-polar induced dipoles. Induced dipole- a weak atracion that results when a polar molecule induces a dipole in an atom or in a nonpolar molecule by disturbing the arrangement of electrons in a nonpolar species. Dipole-dipole- the posiive end of a polar molecule will atract the negaive end of the other molecule and inluence its posiion. Everything has london dispersion forces while other interacions are speciic. A type of force acing between atoms and molecules.
