AIIMS 2019 Chemistry Effect of pH on Solubility MCQ Question
Type: MCQ-conceptual-Medium-Class 11
Which of the following has max. solubility at low pH?
A
B
C
D
Correct Answer
Option A
Detailed Explanation
Sr(OH)₂ is a sparingly soluble compound that dissociates into Sr²⁺ and OH⁻ ions in solution. In an acidic environment, the high concentration of H⁺ ions reacts with OH⁻ ions to form water (H₂O), effectively reducing the concentration of hydroxide ions and allowing more Sr(OH)₂ to dissolve to maintain equilibrium, thus increasing its solubility. Other options are not applicable as they do not provide relevant information or alternative scenarios regarding the solubility of Sr(OH)₂ in acidic solutions. Understanding this equilibrium shift is crucial for grasping the principles of solubility in different pH environments.
