The electrochemical properties of copper, titanium in sulfuric acid and their ions in aqueous solution
are investigated in the potentiodynamic mode by the method of polarization curves. Electrochemical properties of
copper and titanium electrodes in a solution of sulfuric acid involving copper (ІІ) ions and titanium with variable
valency by means of potentiodynamic polarization curves. The recovery of copper (II) ions and the regularity of
dissolution of the electrodes are determined. The reduction wave of tetravalent titanium ions in a solution of sulfuric
acid with copper and titanium electrodes is registered for the first time in the polarization program, and it is indicated
that the reduction wave of trivalent titanium ions in the above electrodes is not registered. It is also determined that
when copper (II) ions are present in the electrolyte composition, the reduction wave of tetravalent titanium ions in
the polarization curve is not registered. It is known that obtaining the main part of copper powders is performed by
electrochemical method [1-12].
