A metal chloride ‘X’, on treatment with H2S in acidic medium gives a black ppt. An
aqueous solution of X when treated with a solution of SnCl2 gives a white ppt turning
grey in excess SnCl2. An aqueous solution of ‘X’ when treated with aqueous solution of
KI gives a red ppt that dissolves in excess KI giving a colourless solution that is used for
the detection of cation Y. Identify ‘X’ and Y with justification. and write all the reactions involved.
also please tell me which book has similar questions with solutions
A very difficuly question because in organic involves many diff compounds
I am guessing this might be Hg Cl2 mercuric chloride with H2S it froms HgS (black) and
HgCl2 + SnCl2 = Hg2Cl2 (white) + SnCl4
Hg2Cl2 + SnCl2 = Hg (grey) + SnCl4
And HgCl2 with KI gives K2HgI4 (Nesslers Reagant) for detecting NH4+ ammonium cation
I have GRB Inorganic chemistry by OP Tandon it has similar questions and hints to approx all problems
The metal chloride is HgCl2. HgCl2+H2S ->HgS+2HCl
HgCl2 +SnCl2 ->Hg +SnCl4
(grey mercury)
HgCl2+2KI -> HgI2 +2KCl
HgI2 is used for detection of presence of NH4+ , so Y=NH4+
Hg Cl2 mercuric chloride with H2S it froms HgS (black) and HgCl2 + SnCl2 = Hg2Cl2 (white) + SnCl4 Hg2Cl2 + SnCl2 = Hg (grey) + SnCl4 And HgCl2 with KI gives K2HgI4 (Nesslers Reagant) for detecting NH4+ ammonium cation
Hg Cl2 mercuric chloride with H2S it froms HgS (black) and
