It is well known that water causes decomposition of Grignard reagents. When these reagents are used, water or moisture should be eliminated. However, it is possible that a very small amount of water, for example, trapped in the walls of the glassware used, can enter the system even in a well-controlled Ar glove box. Therefore, in this work, the effect of very low concentrations of water on Mg deposition from a Grignard reagent-based electrolyte was studied. It was shown that a minute amount of water, although insufficient to cause destruction of the Grignard reagent, affects the overpotential for Mg deposition, resulting in Mg deposits of different morphology. For reproducible and reversible Mg deposition and dissolution, it is desirable that the water content of the electrolyte is kept as low as possible and the electrolyte is left to stand for at least several hours after preparation.
