Chemistry Question from JEE Main 2025 · 23 January, Shift 1

Which of the following happens when NH4OHNH_4OH is added gradually to the solution containing 1 M1 \, \text{M} A2+A^{2+} and 1 M1 \, \text{M} B3+B^{3+} ions? Given: Ksp[A(OH)2]=9×10−10K_{sp}[A(OH)_2] = 9 \times 10^{-10} and Ksp[B(OH)3]=27×10−18K_{sp}[B(OH)_3] = 27 \times 10^{-18} at 298 K298 \, \text{K}.

  • A

    B(OH)3B(OH)_3 will precipitate before A(OH)2A(OH)_2

  • B

    A(OH)2A(OH)_2 and B(OH)3B(OH)_3 will precipitate together

  • C

    A(OH)2A(OH)_2 will precipitate before B(OH)3B(OH)_3

  • D

    Both A(OH)2A(OH)_2 and B(OH)3B(OH)_3 do not show precipitation with NH4OHNH_4OH
