CHAPTER 4: Types of Chemical Reactions Dissolution Precipitation Acids and Bases and their Reactions Oxidation-Reduction ReactionsCHEM 1310 A/B Fall 2006 Dissolution of Ionic CompoundsCHEM 1310 A/B Fall 2006 Dissolution of MoleculesCHEM 1310 A/B Fall 2006 Electrolytes Substances which increase the conductivity of water when they dissolve Usually ionic compounds ( , NaCl), but some molecules can also dissolve into ions ( , acids like HCl, HNO3). Strong bases can also be electrolytes (NH3can split H2O into ions).CHEM 1310 A/B Fall 2006 Solubility Tells how much of something (the solute ) will dissolve into a given solvent Example: incomplete dissolution of sugar in iced tea Observation: hot tea dissolves sugar much easier than iced tea.
