![Alcohol groups, R-OH, act as bases in aqueous solutions. A solution with a pH of 5.0 has a [H+] that is 1/10 as great as a solution with a pH of 6.0 Amino groups, R-NH2, act as acids in aqueous solutions. In an aqueous solution, a lower concentration of free protons, or Ht ions, means a lower pH.](http://img.homeworklib.com/questions/e1747ab0-a250-11eb-8e85-f98a4423c5d0.png?x-oss-process=image/resize,w_560)

Lab 5 Buffers 1. Dissolved ions in salt solutions can act as acids or bases and react with water to produce hydronium ions or hydroxide ions that contribute to the pH of the salt solution. Since strong acids and strong bases completely ionize in solution, the reverse reaction essentially does not occur, meaning that the resulting conjugate base of a strong acid or conjugate acid of a strong base do NOT act as acids or bases. Ions that are conjugate...

(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...
