Question

mercuric chloride reacts with Ammonia gas and forms white precipitate the molecular formula of white precipitate is

Answer 1

NH4Cl (Ammonium chloride) is the formula of white ppt .

Answer 2

Answer: The white precipitate formed is $HgNH_2Cl$

Explanation:

When mercuric chloride reacts with ammonia, it produces a white precipitate of mercuric amido chloride and a black precipitate of mercury with ammonium and chloride ions.

The reaction for the above reaction follows:

$Hg_2Cl_2+2NH_3\rightarrow HgNH_2Cl(s)+Hg(l)+NH_4^++Cl^-$

Hence, the white precipitate formed is $HgNH_2Cl$
