Perhaps the most significant compound of sulfur used in modern industrialized societies is sulfuric acid (H2SO4). Sulfur dioxide (SO2) finds practical applications in bleaching and refrigeration but it is also a nuisance gas resulting from the burning of sulfurous coals. Sulfur dioxide gas then reacts with the water vapor in the air to produce a weak acid, sulfurous acid (H2SO3
) which contributes to the acid rain problem.
(Concentrated sulfuric acid used in forward reaction to remove H and O atoms.)
