Metal surfaces in higher temperatures become more anodic or more cathodic? - ANSWER-Anodic Metal surfaces in higher oxygen concentrations become more anodic or more cathodic? - ANSWER-Cathodic Metal surfaces in higher salt concentrations become more anodic or more cathodic? - ANSWER-Anodic Metal surfaces in higher metal ion concentrations become more anodic or more cathodic? - ANSWER-Cathodic Metal surfaces in higher PH environments become more anodic or more cathodic? - ANSWER-Anodic The potential of a metal surface at a PH of 7 is -500 mV. What would be the potential of the same metal surface in a PH of 8? - ANSWER--560 mV Decrease in the potential difference between the anode and the cathode - ANSWER-Polarization When polarization increases, current and corrosion rate... - ANSWER-Decrease (when polarization is the control factor) When current increases
