SO2 SO3 SO32-怎么比较键角大小? - 知乎
二氧化硫:S原子取 sp2杂化,三对价层电子对理想是呈正三角形,但孤电子对对成键电子对有排斥,所以键角小于120°. 三氧化硫:S取sp2杂化,正三角形结构,键角120°. 亚硫酸根:S取 sp3杂化,键角小于109°28′. 所以,亚硫酸根<二氧化硫<三氧化硫. 比较构型, SO3 是120度。 再看孤对电子的影响, SO2 <120度, SO3 2- <109度28分。 显然,SO3 2-<SO2<SO3. 二氧化硫是 sp2杂化,三氧化硫是sp2杂化,亚硫酸根是 sp3杂化; 二氧化硫有一对孤电子对,三氧化硫 …
Conversion of Sulphur Dioxide to Sulphur Trioxide - Unacademy
In this step, the conversion of sulphur dioxide to sulphur trioxide is done by mixing SO2 with atmospheric oxygen to oxidise it to form SO3 in the presence of V2O5 as a catalyst. 2SO2 (sulphur dioxide) + O2 (oxygen) + [V2O5 (catalyst)] → 2SO3 (sulphur trioxide)
SO2 + O2 = SO3 - Chemical Equation Balancer
SO2 + O2 = SO3 is a Synthesis reaction where two moles of Sulfur Dioxide [SO 2] and one mole of Dioxygen [O 2] combine to form two moles of Sulfur Trioxide [SO 3]
Difference Between SO2 And SO3 | Diffeology
2025年2月7日 · Difference Between SO2 and SO3 is simple to understand. SO2 is a colorless, odorless gas that is stable. SO3 is more reactive and can quickly turn into sulfuric acid. Both are toxic. SO2 is normally present in the air, and SO3 forms when SO2 comes in contact with oxygen.

SO2 vs. SO3 - What's the Difference? - This vs. That
SO2 and SO3 are both sulfur oxides, but they have different chemical compositions and properties. SO2, also known as sulfur dioxide, is a colorless gas with a pungent odor. It is formed by the combustion of sulfur-containing fuels and is a major air pollutant. SO2 is soluble in water and can react with it to form sulfurous acid.
