AIIMS 2019 Chemistry Ionic Product of Water MCQ Question
The value of ionic product of water at is
less than
greater than
equal to
equal to
Correct Answer
Detailed Explanation
The ionic product of water (Kᵥ) increases with temperature due to the endothermic nature of the autoionization of water, represented by the equilibrium reaction: 2 H₂O ⇌ H₃O⁺ + OH⁻. As temperature rises, the equilibrium shifts to the right, producing more hydronium (H₃O⁺) and hydroxide (OH⁻) ions, thus increasing Kᵥ. Since all other options are marked as N/A, they do not provide relevant information or alternative explanations regarding the ionic product of water. Understanding this concept is crucial for grasping the temperature dependence of water's ionization and its implications in acid-base chemistry.
