Why concentrated sulphuric acid, nitric acid, hydrochloric acid in liquid form can also show usual acidic property even though it is not ionize in water in order to obtain hydrogen ions (H+) ?
If they have no hydrogen ions, they cannot show acidic property because hydrogen ions are responsible for acidic property.
I dont understand. Hope someone can help. Thanks!!
Some Chemistry questions !!!

✔ 最佳答案
concentrated sulphuric acid, nitric acid, hydrochloric acid in liquid form 是水溶液 ( aqueous solutions )。所以 show usual acidic property。citric acid 可以是 solid form，就 [ 唔 ] show usual acidic property 了。

solid citric acid + dry pH paper 唔會變色
solid citric acid + solid sodium carbonate 唔會放 CO₂，因為冇 ionization 去放 H⁺。

Hydrochloric acid is the aqueous solution of HCl, while hydrogen chloride is pure HCl. "Hydrochloric acid in pure liquid form" is contradictory.
Besides, at room temperature, hydrogen chloride is gaseous. Under atmospheric pressure, hydrogen chloride condenses to liquid at -85.05°C.

Have you any example to show that pure acid (in the absence of water) exhibits usual acidic property ?
