“…Bismuth(III) oxide is formed at potentials close to E cor . The anodic peak of bismuth related to the formation of BiOCl [1] splits into two; the E value of the second peak coincides with the value characteristic of pure NaCl. The first one is observed at lower E values.…”

“…It was shown previously that bismuth undergoes anodic passivation in neutral chloride media, while the alternation of activation and passivation is due to a variation of the film composition [1]. Benzaldehyde (I), 2-hydroxy-4-methoxybenzaldehyde (II), 3,4dimethoxybenzaldehyde (III), and -bromocinnamaldehyde (IV) differ in solubility, which complicates the comparison of their effect on the electrochemical behavior of bismuth.…”

“…The electrode preparation and experimental technique were described previously [1]. Benzaldehyde (I), 2-hydroxy-4-methoxybenzaldehyde (II), 3,4-dimethoxybenzaldehyde (III), and -bromocinnamaldehyde (IV) were used as additives.…”

“…The regularities of the effect of various types of organic additives on the anodic behavior of bismuth with consideration for stepwise passivation-activation in neutral chloride media were established previously [1,2]. Aromatic aldehydes were not considered as process rate regulators on bismuth but they are known as inhibitors of anodic metal dissolution in neutral media [3,4].…”

The effect of benzaldehyde (I), 2-hydroxy-4-methoxybenzaldehyde (II), 3,4dimethoxybenzaldehyde (III), and -bromocinnamaldehyde (IV) on the partial electrode reactions occurring on bismuth in a neutral chloride solution was investigated. It was established that the dependence of cathodic and anodic process rates on aldehyde concentration is not linear. At equal concentrations, I and III better inhibit cathodic hydrogen evolution than compounds II and IV containing more hydrophilic and hydrophobic substituents, respectively. The aldehydes change the basic parameters of the anodic polarization curve of bismuth. It was shown that dissolution of bismuth in chloride solution with and without the aldehydes studied occurs under diffusion control.

“…1). On tin, depassivation is preceded by two stepwise passivation peaks corresponding to the formation of SnO and SnO 2 [7], whereas depassivation on lead and tin is preceded by intermediate activation due to a decrease in the salt basicity [8,9]. Lead repassivation is caused by the formation of a poorly-soluble normal salt, whereas that of tin and bismuth is due to hydrolysis products, since tin chloride is well soluble and bismuth chloride readily undergoes hydrolysis.…”
