Detection of an acidic (CO2, SO2) or basic (NH3) gas by monitoring a dielectric relaxation of a reaction product (for example of a zwitterion) of an acid-base reaction of the gas with a chemical compound (like DBU) using an integrated circuit...
This marked difference is due to SO3 being a much stronger Lewis acid (pF(-) value of 7.83) than SO2 (pF(-) value of 3.99), thus forming a stronger S-N bond with the Lewis base N-3(-). The geometry of the free gaseous SO2N3- anion was calculated at the RHF, MP2, B3LYP, ...

Lewis acid/base catalyzed [2+2]-cycloaddition of sulfenes and aldehydes: a versatile entry to chiral sulfonyl and sulfinyl derivatives. -sulfones, -sulfonic acids, -sulfinic acids, -sultines, and -sultones or a single stereocenter, such as in -branched alkyl or allyl sulfonic acids... ...
When SO2 remains near the Earth’s surface, it is toxic, causes acid rain, and degrades air quality. It forms sulfate aerosols that can alter cloud reflectivity and precipitation in the free troposphere [1, 2]. As a kind of important atmospheric pollutants, SO2 critically affects the global...

The reaction between SO2 and limewater is an example of an acid-base reaction. SO2is an acidic gas, and when it reacts with the basic solution of calcium hydroxide in limewater, it neutralizes the base and forms a salt (calcium sulfite) and water. ...

Polluted air may cause serious environmental damage, such as acid rain, and health-related problems, such as respiratory diseases, hypertension and out-of-hospital coronary deaths (Dai et al., 2015; Zhang et al., 2014b). In both the 10th (2001–2005) and 11th (2006–2010) Five-Year ...
39 proposed sulfate formation in the reaction of sulfurous acid microdroplet and oxygen, without additional oxidants, and the finding of spontaneously H2O2 production in the atomized bulk water microdroplets by Lee et al.40 may shed light on this phenomenon. These findings demonstrated that there ...
