Electrolytic cells, suitable for depositing a metal on or removing a metal from a substrate, are provided which comprise an anode and cathode, sulfuric acid, an a chalcogen-containing compound soluble in said bath and having the empirical formula ##STR1## wherein X is a chalcogen, each of R.sub.1 and R.sub.2 is selected from hydrogen, NR.sub.3 R.sub.4 and NR.sub.5, at least one of R.sub.1 and R.sub.2 is other than hydrogen, each of R.sub.3 and R.sub.4 is hydrogen or a monovalent organic radical, and R.sub.5 is a divalent organic radical, in which the molar ratio of the chalcogen compound to sulfuric acid is about 1 or more, and the molar ratio of water to the combination of acid and chalcogen compound is about 20 or less. These cells enable the use of higher concentrations of sulfuric acid than would otherwise be possible, minimize hydrogen and/or oxygen evolution at the electrodes with attendant advantages, and are useful in a variety of methods such as electroplating (including immersion plating), electroforming, electrolytic machining, electropolishing, electrolytic roughening, anodizing, electrowinning and as storage batteries.
