Calculate the pH of a 0.105 M solution of ethylenediamine (H,NCH,CH,NH,). The pKa values for the acidic form of ethylenediamine (H;NCH,CH,NH† ) are 6.848 (pKa1) and 9.928 (pK2). pH Calculate the concentration of each form of ethylenediamine in this solution at equilibrium. [H,NCH,CH,NH,] = M [H,NCH,CH,NH; ] = M [H}NCH,CH,NH†1 = M
