Strong acids and strong bases ionize 100% in aqueous solution. 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). - NH3 is a weak base. In solution we write it as NH3(aq). Exception: Since Ca(OH), 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 Bases LIOH, NaOH, КОН Strong Acids HCІ, HBr, HI HNO3 Ca(OH)2 (slightly soluble) HCIO4 Ba(OH)2 H2SO4 Sr(ОН)2
Chemistry The degree to which a weak base dissociates is given by the base-ionization constant, Kb. For the generic weak base, B B(aq) + H₂O(1) BH (aq) + OH(aq) this constant is given by Kb = BH+|OH| [B] Strong bases will have a higher Kb value. Similarly, strong bases will have a higher percent ionization value. Percent ionization = [OH] equilibrium [B] initial x 100% Strong bases, for which K, is very large, ionize completely (100 %). For weak bases, the percent ionization changes with concentration. The more dilute the solution, the greater the percent ionization.
