The dissociation of HCl or HNO3 to form hydrogen ions always occurs in the presence of water. Hydrogen ions (H⁺) combine with H2O to form hydronium ions (H3O⁺). The reaction is as follows: HCl + Water → H ⁺ + Cl – H ⁺+ H₂O → H₃O + Although aqueous solutions of glucose and alcohol contain hydrogen, tRead more

Although aqueous solutions of glucose and alcohol contain hydrogen, these cannot dissociate in water to form hydrogen ions. Hence, they do not show acidic character.

Hydrogen gas is usually liberated when an acid reacts with a metal. Take few pieces of zinc granules and add 5 ml of dilute H2SO4. Shake it and pass the gas produced into a soap solution. The bubbles of the soap solution are formed. These soap bubbles contain hydrogen gas. 𝑍𝑛+2𝐻₂𝑆𝑂₄ → 𝑍𝑛(𝑆𝑂4) ₂ +2𝐻₂Read more
