Abstract

"The anodic dissolution of molybdenum in 1.0 N HNO₃ (pH = 0.3) , 0.1 N HNO₃-0.9 N KNO₃ (pH = 1.2), and 0.01 N HNO₃ -0.99 N KNO₃ (pH = 2.1) was investigated. The following conclusions were possible: 1. Mo is in general electrochemically oxidized to the Mo-VI state during anodic dissolution. 2. The resultant ions in solution are HMOO⁻₄. 3. The Mo surface in aqueous solutions is covered with an oxide whose approximate composition is Mo₂O₅. 4. The polarization curves have a linear Tafel region at potentials slightly above the rest potential. 5. There is no significant effect of pH on the anodic dissolution. 6. The anodic dissolution is controlled by the oxidation of the surface oxide (Mo₂O₅) to MoO₃"--Abstract, Page ii.
