Calculate the pH for an aqueous solution of pyridine that contains 2.15 × 10-4 M hydroxide ion.

Solutions

Expert Solution

Hydroxide ion concentration, [OH] = 2.15*10-4

                                         POH = - Log[OH]

                                                = - Log[2.15*10-4]

                                        POH = 3.67

But ,                                PH = 14 - POH

                                                           = 14 -3.67

                                      PH = 10.3
