Question
**Equilibrium in a Saturated Solution of \( \text{Cr}_2(\text{SO}_4)_3 \)** **Question:** Which of the following represents the equilibrium in a saturated solution of \( \text{Cr}_2(\text{SO}_4)_3 \)? **Options:** 1. \( \text{Cr}_2(\text{SO}_4)_3 \text{ (s) } \leftrightharpoons 2 \text{Cr}^{3+} \text{ (aq) } + 3 \text{SO}_4^{2-} \text{ (aq)} \) 2. \( \text{Cr}_2(\text{SO}_4)_3 \text{ (s) } \leftrightharpoons 2 \text{Cr}^{2+} \text{ (aq) } + 3 \text{SO}_4^{3-} \text{ (aq)} \) 3. \( \text{Cr}_2(\text{SO}_4)_3 \text{ (s) } \leftrightharpoons \text{Cr}^{3+} \text{ (aq) } + \text{SO}_4^{2-} \text{ (aq)} \) --- **Explanation:** This question tests the understanding of chemical equilibrium in a saturated solution, specifically for \( \text{Cr}_2(\text{SO}_4)_3 \). Equilibrium represents a state where the rate of dissolution of the solid equals the rate of precipitation from the solution. The correct equation will show the dissociation of \( \text{Cr}_2(\text{SO}_4)_3 \) (solid) into its constituent ions in aqueous form at equilibrium. 1. The first option shows \( \text{Cr}_2(\text{SO}_4)_3 \) dissociating into 2 chromium ions (with a +3 charge each) and 3 sulfate ions (with a -2 charge each). 2. The second option suggests the formation of chromium ions with a +2 charge and sulfate ions with a -3 charge, which does not match the correct stoichiometry and charges for these ions in this context. 3. The third option shows a 1:1 ratio of chromium ion to sulfate ion dissociation, which is incorrect as it does not balance the equation properly for the given compound. Thus, the most accurate
