General description

Sulfuric acid is a strong mineral acid. It participates as a medium in the anodic oxidation of aniline at a platinum electrode. Anodic oxidation has been reported to proceed via a free radical mechanism and octamer emeraldimine has been obtained as a major product.

Application

Sulfuric acid solution has been used as a solvent for the preparation of 1M xylenol orange and 2.5mM ammonium ferrous sulfate solution in a study.

It has been proposed that sample storage may have some influence on the parameters of oxidative stress status (OSS) in biological fluids. We measured four important OSS parameters in plasma of 23 healthy subjects and repeated the measurements in the

Atmospheric new-particle formation affects climate and is one of the least understood atmospheric aerosol processes. The complexity and variability of the atmosphere has hindered elucidation of the fundamental mechanism of new-particle formation from gaseous precursors. We show, in experiments performed

Nucleation of aerosol particles from trace atmospheric vapours is thought to provide up to half of global cloud condensation nuclei. Aerosols can cause a net cooling of climate by scattering sunlight and by leading to smaller but more numerous cloud

Atmospheric aerosols formed by nucleation of vapors affect radiative forcing and therefore climate. However, the underlying mechanisms of nucleation remain unclear, particularly the involvement of organic compounds. Here, we present high-resolution mass spectra of ion clusters observed during new particle
