Based on the values of the oxidation of the atoms of the corresponding chemical elements, provide a reasoned answer to the question: which of the two hydroxides is the stronger basis? CuOH or Cu(OH)2; Fe(OH)2 or Fe(OH)3; Sn(OH)2 or Sn(OH)4. Write the equations for the chemical reactions that prove the amphoteric state (II) of the hydroxide
