Definitions Strong Acids HCl HBr HI HNO3 HClO4 H2SO4 • Acid: a species that supplies H+ ions to water • Strong acid: an acid that completely ionizes in water forming an H+ ion and an anion • Weak acid: an acid that only partially ionizes in water to give an H+ ion and an anion
Definitions Strong Bases LiOH NaOH KOH Ca(OH)2 Sr(OH)2 Ba(OH)2 • Base: a species that supplies OH- ions to water • Strong Base: a base that completely ionizes in water forming a OH- ion and a cation • Weak base: a base that is only partially dissociated to form OH- ions in water • Weak bases react with water and the OH- comes from the water. The remaining H+ ion form the water attaches itself to the weak base.
Writing Equations for Acid-Base Reactions Write the net ionic equation between citric acid, H3C6H5O7 and sodium hydroxide. General form: HB + OH- B- + H2O H3C6H5O7 + OH-H2C6H5O7- + H2O Write the net ionic equation for phenylaniline, C6H5NH2 and hydroiodic acid. C6H5NH2 + H+ C6H5NH3+ Write the net ionic equation for potassium hydroxide and perchloric acid. OH- + H+ H2O Write the net ionic equation for barium hydroxide and ascorbic acid, HC6H7O6.
