In lab, you're having fun along with buffers based onto a 0.1 M solution of sodium phosphate at pH7.0. Into this system, there are three of pK A s as: 12.7, 7.21 and 2.12.
Energy of the electron in Hydrogen atom is given by: (1) E n = 131.38/ n 2 x kj mol -1 (2) E n = 131.33/n xkj mol -1 (3) E n = 1313.3/ n 2 x kj mol
