A procedural change would be essential if a boy want to determine the tomato juice's acidity by titrating a sample of juice with NaOH(sodium hydroxide) solution Briefly explain What change would you make to the procedure ?
The difference between the energy of the photons and the kinetic energy of the electrons corresponds to the energy needed to remove the electrons (that is, the ionization energy). Suppose that a PES experiment is performed in which mercury vapor i..
