• Description: 1-Butyl-3-methylimidazolium hydrogen sulfate is an acidic ionic liquid. [BMIM][HSO4] can be used as an additive to accelerate current efficiency, lower power consumption, and enhance the surface morphology during the electrodeposition of zinc from acidic sulfate solutions. The combination of sodium nitrate and [BMIM][HSO4] can be used as a nitrating agent for the selective nitration of phenols to afford its corresponding nitro derivatives.
