Chemistry Question from JEE Main 2026 · 21 January, Shift 1

Consider the following reactions. PbCl2+K2CrO4→A+2KClPbCl_2 + K_2CrO_4 \rightarrow A + 2KCl (Hot solution) A+NaOH→B+Na2CrO4A + NaOH \rightarrow B + Na_2CrO_4 PbSO4+4CH3COONH4→(NH4)2SO4+XPbSO_4 + 4CH_3COONH_4 \rightarrow (NH_4)_2SO_4 + X

In the above reactions, A, B and X are respectively:

  • A

    Na2[Pb(OH)2]Na_2[Pb(OH)_2], PbCrO4PbCrO_4 and (NH4)2[Pb(CH3COO)4] (NH_4)_2[Pb(CH_3COO)_4]

  • B

    Na2[Pb(OH)2]Na_2[Pb(OH)_2], PbCrO4PbCrO_4 and [Pb(NH3)4]SO4[Pb(NH_3)_4]SO_4

  • C

    PbCrO4PbCrO_4, Na2[Pb(OH)4]Na_2[Pb(OH)_4] and [Pb(NH3)4]SO4[Pb(NH_3)_4]SO_4

  • D

    PbCrO4PbCrO_4, Na2[Pb(OH)4]Na_2[Pb(OH)_4] and (NH4)2[Pb(CH3COO)4] (NH_4)_2[Pb(CH_3COO)_4]
