OWL Strong Acids and Strong Bases ionize 100% in aqueous solution. (consistent with table 6.2 p 246) - HCl is a strong acid. In solution we write it as H + (aq) + Cl - (aq). - HF is a weak acid. In solution we write it as HF(aq). - KOH is a strong base. In solution we write it as K + (aq) + OH - (aq). - NH 3 is a weak base. In solution we write it as NH 3 (aq). Exception: Since Ca(OH) 2 is only slightly soluble we write it as Ca(OH) 2 (s). Below is a list of the 6 strong acids and 6 strong bases you should know. All other acids and bases are considered weak. Strong Acids HCl, HBr, HI HNO 3 HClO 4 H 2 SO 4 Strong Bases LiOH, NaOH, KOH Ca(OH) 2 slightly soluble Ba(OH) 2 Sr(OH) 2 OWL Binary Acid Nomenclature Binary compounds are composed of two elements. When one of the elements is hydrogen a binary acid can be formed. Examples of this are HCl or H 2 S. When put into water, binary acids give H + (aq), which makes the solution acidic.

Unformatted text preview: There are two ways to name these compounds: 1. Molecular Name : Hydrogen + anion name 2. Acid Name : Hydro ____ ic acid. Used for aqueous solutions of the compound. Molecular Name ... Acid Name HCl hydrogen chloride hydrochloric acid H 2 S hydrogen sulfide hydrosulfuric acid There is one additional substance that is named like a binary compound although it is composed of three elements instead of two. HCN = hydrocyanic acid or hydrogen cyanide. OWL Oxo Acid Nomenclature Oxo acids are composed of H + + an oxygen containing anion. For example: HNO 3 or H 2 SO 4 . You MUST LEARN your polyatomic anions in order to name these acids. Recall that oxygen containing anions end in either ate or ite . Learn the ate anions and all the rest follow. ate anions form ic acids. HNO 3 = nitr ic acid ite anions form ous acids. HNO 2 = nitr ous acid...
