NACE CP 2 Concepts exam 2023 with 100% correct answers
Metal surfaces in higher temperatures become more anodic or more cathodic? Anodic Metal surfaces in higher oxygen concentrations become more anodic or more cathodic? Cathodic Metal surfaces in higher salt concentrations become more anodic or more cathodic? Anodic Metal surfaces in higher metal ion concentrations become more anodic or more cathodic? Cathodic Metal surfaces in higher PH environments become more anodic or more cathodic? 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? -560 mV Decrease in the potential difference between the anode and the cathode Polarization When polarization increases, current and corrosion rate... Decrease (when polarization is the control factor) When current increases, polarization... Increases (when current is the control factor) When temperature increases, polarization... Decreases (and current increases) When movement in the electrodes and the electrolyte increases, polarization... Decreases (and current increases) When there is an increase in anodic metal ion concentration, polarization... Increases (and current decreases) When there is an increase in cathodic metal ion concentration, polarization... Decreases (and current increases)
