NEET Chemistry Ionization Constants MCQ Question
Kₐ, Kₓ and Kₑ are the respective ionisation constants for the following reactions. H₂S ⇌ H⁺ + HS⁻ HS⁻ ⇌ H⁺ + S²⁻ H₂S ⇌ 2H⁺ + S²⁻ The correct relationship between Kₐ, Kₓ and Kₑ is
Kₑ = Kₐ × Kₓ
Kₑ = Kₐ + Kₓ
Kₑ = Kₐ − K²ₓ
Kₑ = Kₐ / Kₓ
Correct Answer
Detailed Explanation
The overall ionization constant Kₑ for the complete ionization of H₂S is the product of the individual ionization constants: Kₑ = Kₐ × Kₓ.
