  • 1. KoolaidSugar/mix + Water  Grape Koolaidesolute  solvent solution REACTANTS PRODUCTSolution - evenly distributed (window cleaner)Colloid- particles scatter light (milk; fog)Suspension - visible particles (snow globe; vinegrette)p693Na+Cl- +H+2O- H+Cl- + Na+(OH-)salt + solvent  acid + baseWife Swap - Double Displacement (replacement)
  • 2. ConcentrationDilute - little soluteConcentrated - lot soluteSolubitity - how much solute can be dissolved by a 
certainamount of solvent at a certain temperaturesaturated can not add anymoreunsaturated can add moresupersaturated over the amount (rock candy)Affect solubility- temperature pressure type of solvent ( Nail water/acid)
