Which of the following parameters or physical processes can demonstrably increase the solubility of — Ionic Equilibrium Chemistry Question

💡 Solution & Explanation

Adding a complexing agent removes $M^+$ from the equilibrium, shifting dissolution forward (increasing solubility). Adding $H^+$ removes $X^-$ by forming weak acid $HX$, also shifting dissolution forward. Increasing temperature increases $K_{sp}$ for endothermic dissolutions, raising solubility. Conversely, adding a common ion drastically suppresses and decreases solubility via Le Chatelier's principle.
