Fundamentals: J Acids and Bases Acid – proton donor Base – proton acceptor What is a proton? Hydrogen ion (H + ) Hydrogen atom has: 1 proton 1 electron 0 neutrons When H becomes H + (loses e - ) it only has 1 proton H 3 0 + – hydronium ion When water gains a proton H 2 O (l) + H + H 3 0 + (aq) Ex. HCl (Aq) + H 2 O (l) H 3 0 + (aq) + Cl - HCl – lost (donated) a proton ACID H 2 O – gained (accepted) a proton BASE Neutralization: Reaction between an acid and a base, produces a salt and water HCl (aq) + NaOH (aq) → NaCl (aq) + H 2 O (l) The cation of the salt is provided by the base The anion of the salt is provided by the acid Naming Acids: Naming acids depend on whether or not the anion contains oxygen Anion does not contain oxygen: Prefix “hydro-“ Suffix “-ic” Attached to element name of the anion HCl: gas – hydrogen chloride Acid – hydrochloric acid Anion does contain oxygen (oxyanion) -ate: suffix “-ic” H 2 S0 4 : dihydrogen sulfate Acid – sulfuric acid -ite: suffix “-ous” H 2 SO 3 : dihydrogen sulfite Acid – sulfurous acid
