✦ Synopsis
w -The corrosion and polarization cbaractistics of zinc have been studied in molar, quiescent solutions of NH&lo,, (NH&SO+, NH&l and NH,Br in the pH range 3.8-5.8. Corrosion rates have been determined by the Tafel line extrapolation procedure and the polarization resistance. method where possible. Numerical values of the corrosion currents are compared. The role of NH: ions, anions, pH and battery zinc alloying constituents on the nature of the rate controlling anodic and cathodic processes are discussed.
