Question

Write the acidic equilibrium equation for HNO₂

Answer 1

The acidic equilibrium equation for HNO₂ in water is HNO₂(aq) + H₂O(l) ⇌ H₃O⁺⁺(aq) + NO₂⁺(aq), illustrating the partial ionization of nitrous acid into hydronium and nitrite ions in an equilibrium state.

Step-by-step explanation:

The acidic equilibrium equation for HNO₂ represents its partial ionization in water. The equation is often written as:

HNO₂(aq) + H₂O(l) ⇌ H₃O⁺⁺(aq) + NO₂⁺(aq)

This reaction indicates that nitrous acid (HNO₂) donates a proton to water, forming hydronium ions (H₃O⁺⁺) and nitrite ions (NO₂⁺) in an equilibrium process.

As a weak acid, HNO₂ does not dissociate completely in solution. Therefore, this reaction represents an equilibrium, and not all of the HNO₂ molecules will ionize. The equilibrium constant (Ka) for this reaction helps to quantify the extent of ionization.

Answer 2

h+(aq)+no−2(aq)⇌hno2(aq)2. hno2(aq)⇌h+(aq)+no−2(aq)3. hno2(aq)⇌h−(aq)+no+2(aq)4. hno2(aq)+h+(aq)⇌h2no+2(aq)5. hno2(aq)+h−(aq)⇌h2no+2(aq)​b.
