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...
On the surface of the packing, the gas-liquid two phases fully contact, absorb and neutralize the reaction, and adsorb the acidic or basic pollutants contained in the exhaust gas. After the acid mist exhaust gas is purified, the clean gas is dehydrated and defogged by the demister ...
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. This reaction is often used as a test for the presence of SO2 gas. When SO2 is bubbled through limewater, the ...
recommended videos properties of sulphur dioxide it is a colourless gas with a rotten egg odour. it is highly soluble in water. it liquefies easily. so 2 dissolves in water to form sulphurous acid due to which it possesses an acidic character. h 2 o + so 2 → h 2 so 3 it ...

This paper summarises basic studies on the mechanism of SO 2/O 2 oxidation, the kinetics of oxidation in acidic media, and potential applications in hydrometallurgy. The SO 2/O 2 system readily oxidises Fe(II) to Fe(III) and provides a simple method of regenerating Fe(III) for leaching ...
To determine the bleaching action of sulfur dioxide (SO₂), we need to analyze its properties and how it interacts with other substances. Here’s a step-by-step breakdown of the reasoning:Step 1: Understanding Bleaching Bleac

SO2 was acidic gas in the reaction gas. In order to promote the adsorption of SO2 on the catalyst surface, the catalyst was required to have relatively weak acidity and strong basicity. Therefore, NH3-TPD (Fig. 2(a) and (b)) and CO2-TPD (Fig. 2(c) and (d)) were used to charact...
