Question

Consider a solution containing lead ions (Pb^2+). Which of those same fourteen solutions would cause a precipitate to form when mixed with this lead ion solution?

Use the fourteen solutions below.

AICIE N Hg BaCl2 CuSO4 FeCl3 HCI Pb(NO3)2 HNO3 KI AgNO3 Na co NaOH Na3PO4 H2SO4

Answer 1

Ans: The precipitation or no precipitation, when the Pb2+ solution is mixed with the above 14 solutions are mentioned below with ppt formula:

AlCl3   -- White precipitate – PbCl2

NH3   -- White precipitate – Pb(OH)2

BaCl2 -- White precipitate – PbCl2

CuSO4 -- White precipitate – PbSO4

FeCl3   -- White precipitate – PbCl2

HCl -- White precipitate – PbCl2

Pb(NO3)2             -- No precipitate                  

HNO3                   -- No precipitate

KI -- Bright yellow precipitate – PbI2

AgNO3                 -- No precipitate

Na2CO3   -- White precipitate – PbCO3

NaOH -- White precipitate – Pb(OH)2

Na3PO4     -- White precipitate – Pb3(PO4)2

H2SO4   -- White precipitate – PbSO4
