Ionic Equilibrium question

2025 · 23 Jan · Shift 1 · Q13

JEE MainChemistryIonic EquilibriumMCQ+4 / −1
Which of the following happens when NH4OH\mathrm{NH}_4 \mathrm{OH}NH4​OH is added gradually to the solution containing 1 M A2+\mathrm{A}^{2+}A2+ and 1MB3+1 \mathrm{M} \mathrm{B}^{3+}1MB3+ ions? Given : Ksp [A(OH)2]=9×10−10\mathrm{K}_{\text {sp }}\left[\mathrm{A}(\mathrm{OH})_2\right]=9 \times 10^{-10}Ksp ​[A(OH)2​]=9×10−10 and Ksp[B(OH)3]=27×10−18\mathrm{K}_{\mathrm{sp}}\left[\mathrm{B}(\mathrm{OH})_3\right]=27 \times 10^{-18}Ksp​[B(OH)3​]=27×10−18 at 298 K.
  1. A
    A(OH)2\mathrm{A}(\mathrm{OH})_2A(OH)2​ will precipitate before B(OH)3\mathrm{B}(\mathrm{OH})_3B(OH)3​
  2. B
    A(OH)2\mathrm{A}(\mathrm{OH})_2A(OH)2​ and B(OH)3\mathrm{B}(\mathrm{OH})_3B(OH)3​ will precipitate together
  3. C
    Both A(OH)2\mathrm{A}(\mathrm{OH})_2A(OH)2​ and B(OH)3\mathrm{B}(\mathrm{OH})_3B(OH)3​ do not show precipitation with NH4OH\mathrm{NH}_4 \mathrm{OH}NH4​OH
  4. D
    B(OH)3\mathrm{B}(\mathrm{OH})_3B(OH)3​ will precipitate before A(OH)2\mathrm{A}(\mathrm{OH})_2A(OH)2​
