Phenol, C6H5OH, is used as a disinfectant. The pH of an aqueous phenol solution was measured at 4.72. Is phenol acidic; neutral or basic. Calculate the [H3O+], [OH-] and pOH of the solution?
On a shelf in the lab storeroom marked “Solutions of Acids”, a bottle has a torn label. All that can be seen on the label is the concentration: 643 x 10-3 M, not the name of the acid. In trying to find the identity of the acid, you measure the pH of this solution and find it to be 3.382. Of the acids listed on the chart of Acid Dissociation Constants (attached), WHICH ACID could this be? There is only one correct answer. Hint: Use the given information to find Ka. Use all sig figs in the pH.

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.
