Explanation:
The acidic equilibrium equation for nitrous acid is shown as HNO₂ ⇄ H⁺ + NO₂⁻ in which acid is in equilibrium with its dissociate ions.
Equilibrium state in any chemical reaction is that state in which concentration of reactant and products will attain constant value.
Acidic equilibrium equation for Nitrous acid (HNO₂) is shown as:
HNO₂ ⇄ H⁺ + NO₂⁻
From the above equation it is clear that in equilibrium state concentration of nitrous acid is in equilibrium with the H⁺ ion and NO₂⁻ ion.
Hence, HNO₂ ⇄ H⁺ + NO₂⁻ is the acidic equilibrium equation.
