GENERAL CHEMISTRY CHAPTER 4 – REACTIONS IN AQUEOUS SOLUTION PAGE 1 OF 35 Solutions Homogeneous mixture = When table salt is mixed with water, it seems to disappear, or become a liquid solution The mixture is homogeneous The NaCl (s) = solute = component that dissolves Solvent = component that dissolves the solute Many times, the chemicals we are reacting together are dissolved in water Aqueous Solutions Mixtures of a chemical dissolved in water = aqueous Dissolving the chemicals in water helps them to react together faster solutions The water separates the chemicals into individual molecules or ions The separate, free-floating particles come in contact more frequently so the reaction speeds up Dissociation When polyatomic ions dissociate , the polyatomic group stays together as one ion = the separation of ionic compounds in water What happens when a solute dissolves? There are attractive forces between the solute particles holding them together There are also attractive forces between the solvent molecules When we mix the solute with the solvent, there are attractive forces between the solute particles and the solvent molecules If the attractions between solute and solvent are strong enough, the solute will dissolve
