The formula of fuming sulfuric acid is: a) H2SO4.SO3 b) H2SO4.SO2 c) H2SO4.HSO2 d) H2SO4.HSO3 e) H2SO4.SO Why does it take more NaOH to neutralize H2SO4 than in HCl? 1. Why H2SO4 is strong acid than H2SO3? 2. Why HClO2 is strong acid than HClO? 3. Why HClO is...
**Particulate matter (PM10) is a major component of air pollution that threatens both our health and our environment. It consists of very small liquid and solid particles floating in the air. **Sulfur dioxide(SO2) acts as an acid.Inhalation(吸入) results in labored breathing, coughing, or ...
Sulfuric acid (H2SO4) is a strong acid that is produced in large quantities industrially. The contact process uses a vanadium(V) oxide (V2O5) catalyst to convert sulfur and oxygen to sulfur trioxide. When this sulfur trioxide is mixed with water, it forms sulfuric acid....
a1310 cm-1是磺酸基的SO2伸缩吸收峰,1193 cm-1和1142 cm-1是磺酸基的S=O不对称和对称伸缩振动吸收峰。 1310 cm-1 is the sulfo group SO2 expansion and contraction absorption peak, 1193 cm-1 and 1142 cm-1 are the sulfo group S=O not symmetry and the symmetrical expansion and contraction ...

What ions and / or molecules are present in relatively large proportions in a solution of a strong acid HI (aq)? Which of the following acids will have the highest K_a value? a) NaH b) H_2S c) H_2S Which of the fol...
They determined that the SO2F2- mediated acid activation forms a transient anhydride intermediate that transforms into the analogous acyl fluoride. They also report that tetrabutylammonium chloride or bromide accelerate the formation of acyl fluoride. ReactIR measurements provided insight into the mechanism...
The formation mechanism of aerosol sulfate during wintertime haze events in China is still largely unknown. As companions, SO2 and transition metals are mainly emitted from coal combustion. Here, we argue that the transition metal-catalyzed oxidation of
Membranes comprising an aromatic ether ketone polymer (e.g. polyetherketone) in sheet or hollow fibre form are made by preparing at least a 12 wt % solution of the polymer in a solvent which is chemically inert to the polymer (e.g. concentrated sulphuric acid); forming a film of the sol...
