Aim: What is a solution and how can we predict when one will form? QQ: NONE! Do Now: Brainstorm at least 3 things you know about solutions. Solutions: a homogenous mixture composed of 2 or more substances Homogeneous mixtures: The same throughout Do not have visibly distinguishable parts Well mixed/blended Solute: the material that is dissolved (often a solid) Solvent: the material doing the dissolving (often a liquid) Soluble: able to dissolve in the solvent Insoluble: not able to dissolve in the solvent “Likes dissolve likes” In order for substances to dissolve in one another, they must have the same polarity. Solute and solvent molecules have to be attracted to one another Polar Molecules: Have a positive end and a negative end Strong attraction between molecules Hydrogen bonding Dipole-dipole bonding Nonpolar Molecules: Highly symmetrical with no separation of charge Weak attraction between molecules London dispersion forces
