1127. Determine the possibility of metal corrosion at a standard pressure and temperature of 298 K in an aerated aqueous solution with a specified pH value. Make a diagram of a corrosive element, write the equations of electrode processes and current-forming reaction. Calculate the EMF of the element and the standard Gibbs energy ΔrG0298 of the corrosion process. Take the relative activity of the corroding metal ions to be 10-6.
No. Metal f0(Mez /Me),B a pH
