Title: Complex compounds of molybdenum in concentrated sulfuric acid in the presence of quinol
Abstract: A polarographic and spectrophotometric study was made of molybdenum in concentrated sulfuric acid in the presence of quinol (H2Q). Four waves are produced in 0.16–7.8 M sulfuric acid. Only a single well-defined, irreversible wave, due to a two-electron reduction (Mo(V)-Mo(III)) (diffusion controlled, with diffusion current proportional to molybdenum concentration) is produced in 81.1% sulfuric acid in the presence of 0.06 M quinol at E1/2=−0.309 V (vs. mercury-pool electrode). Quinol acts as a maxima suppressor for molybdenum maxima and as a complexing agent. The complex formed, as shown by Job's method, has the composition 2Mo(V):H2Q.
