4. Important Chemical Properties
Sulphuric acid has several important chemical characteristics.
๐๐ญ๐ซ๐จ๐ง๐ ๐๐๐ข๐:
It readily dissociates in water, particularly its first proton:
๐โ๐๐โ โ ๐โบ + ๐๐๐โโป
๐๐๐ก๐ฒ๐๐ซ๐๐ญ๐ข๐ง๐ ๐๐ ๐๐ง๐ญ:
Concentrated sulphuric acid has a strong affinity for water and can remove water from many organic materials.
๐๐๐๐๐ญ๐ข๐จ๐ง ๐ฐ๐ข๐ญ๐ก ๐ฆ๐๐ญ๐๐ฅ๐ฌ:
Depending on concentration and conditions, sulphuric acid can react with metals to produce sulfates and hydrogen or sulfur-containing reduction products.
๐๐ข๐ ๐ก๐ฅ๐ฒ ๐๐ฑ๐จ๐ญ๐ก๐๐ซ๐ฆ๐ข๐ ๐๐ข๐ฅ๐ฎ๐ญ๐ข๐จ๐ง:

The primary industrial process is the ๐๐จ๐ง๐ญ๐๐๐ญ ๐๐ซ๐จ๐๐๐ฌ๐ฌ.
The simplified sequence is:
๐๐ฎ๐ฅ๐๐ฎ๐ซ โ ๐๐ฎ๐ฅ๐๐ฎ๐ซ ๐๐ข๐จ๐ฑ๐ข๐๐ (๐๐โ)
๐๐โ โ ๐๐ฎ๐ฅ๐๐ฎ๐ซ ๐ญ๐ซ๐ข๐จ๐ฑ๐ข๐๐ (๐๐โ)
๐๐โ โ ๐๐ฎ๐ฅ๐ฉ๐ก๐ฎ๐ซ๐ข๐ ๐๐๐ข๐ (๐โ๐๐โ)
The key catalytic oxidation step is:
2 ๐๐โ + ๐โ โ 2 ๐๐โ
A ๐ฏ๐๐ง๐๐๐ข๐ฎ๐ฆ(๐) ๐จ๐ฑ๐ข๐๐ (๐โ๐โ
) catalyst is commonly used.
Industrial SOโ is then absorbed in concentrated sulphuric acid to form oleum, which is subsequently adjusted with water to obtain the desired acid concentration.
6. Sulphuric Acid as a Commercial Product
If you are considering ๐ฌ๐ฎ๐ฅ๐ฉ๐ก๐ฎ๐ซ๐ข๐ ๐๐๐ข๐ ๐๐จ๐ซ ๐ฌ๐ฎ๐ฉ๐ฉ๐ฅ๐ฒ ๐ญ๐ก๐ซ๐จ๐ฎ๐ ๐ก ๐๐ฐ๐๐ฌ๐ญ๐ข ๐๐ฑ๐ฉ๐จ๐ซ๐ญ๐ฌ, it is important to specify more than just 'Sulphuric Acid.'
A proper product specification should normally identify:
๐๐ซ๐จ๐๐ฎ๐๐ญ: Sulphuric Acid
๐
๐จ๐ซ๐ฆ๐ฎ๐ฅ๐: HโSOโ
๐๐๐: 7664-93-9
๐๐จ๐ง๐๐๐ง๐ญ๐ซ๐๐ญ๐ข๐จ๐ง: e.g., 98% w/w
๐๐ซ๐๐๐: Industrial / AR / Reagent / High Purity
๐๐๐๐ค๐๐ ๐ข๐ง๐ : Appropriate acid-resistant packaging
๐๐๐: Certificate of Analysis available
๐๐๐: Safety Data Sheet available
