Chemistry

A buffer is prepared by adding 108 mL of 0.48 M NH3 to 143 mL of0.30 M NH4NO3. What is the pH of the final solution?

no of moles of NH3 = molarity * volume in L

                                = 0.48*0.108   = 0.05184 moles

no of moles of NH4Cl   = molarity * volume in L

                                    = 0.3*0.143   = 0.0429moles

Pkb of NH3 = 4.75

   POH = Pkb + log[NH4NO3]/[NH3]

           = 4.75 + log0.0429/0.05184

          = 4.75-0.0822   = 4.6678

PH   = 14-POH

        = 14-4.6678   = 9.3322 >>>>answer
