Consider the following reactions. PbCl_2+K_2 CrO_4 \rightarrow A+2 KCl (Hot solution) A+NaOH ⇌ B+Na_2 CrO_4 PbSO_4+4 CH_3 COONH_4 \rightarrow (NH_4) _2 SO_4+X In the above reactions, A , B and X are respectively. [21 Jan 2026 Shift 1]

Correct Answer is : PbCrO4,Na2[Pb(OH)4] and (NH4)2[Pb(CH3COO)4]

Na _2 [Pb( OH )_2] , PbCrO _4 and [ Pb ( NH _3) _4] SO _4

Na _2 [Pb( OH )_2] , PbCrO _4 and ( NH _4) _2 [Pb ( CH _3 COO ) _4]

PbCrO _4, Na _2 [Pb( OH )_4] and ( NH _4) _2 [Pb ( CH _3 COO ) _4]

PbCrO _4, Na _2 [Pb( OH )_4] and [ Pb ( NH _3) _4] SO _4
