what is solution ? (References) 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)2 is only slightly soluble...
Determining Ionic StrengthUnlike strong acids and bases that ionize completely in solution, weak acids or bases partially ionize. The tendency to ionize (i.e., the ionic strength) of a weak acid or base can be quantified in several ways includingKa or Kb,pKa or pKb,and percent ionization.Part APyridine is a weak base that is used in the manufacture of pesticides and plastic resins. It is also a component of cigarette smoke. Pyridine ionizes in water as follows:C5H5N+H2O?C5H5NH++OH?The pKb of pyridine is 8.75....

When a strong acid-strong base neutralization reaction is also a limiting reactant situation, the leftover reactant will determine your final solution pH. Remember that a limiting reactant indicates that you will run out of one reactant first. Considering the reaction of potassium hydroxide and hydrobromic acid, notice that if you have excess acid leftover it would react with water to produce H3O+ ions in solution: HBr + H2O → Br- + H3O+ If you have excess base left over, it...
