What is the precipitate from the following reaction
NH4Cl(aq) + Hg2(C2H3O2)2(aq) -->
a. Hg2Cl2(aq)
b. Hg2Cl2(s)
c. NH4C2H3O2(aq)
d. NH4C2H3O2(s)
e. NH4Hg2(aq)
f. NH4Hg2(s)
g. NH4(C2H3O2)2(aq)
h. NH4(C2H3O2)2(s)
Explanation / Answer
2 NH4Cl (aq) + Hg2 (C2H3O2)2(aq) --------à Hg2Cl2(s) + 2 NH4C2H3O2(aq)
ALL the correct products for the reaction are b. Hg2Cl2(s) and c. NH4C2H3O2 (aq)( It is Double displacement reaction.)
The spectator ions in the reaction are c. NH4+ and d. C2H3O2-
(Spectator ions are present in the same form throughout the reaction.)
NH4 + +Cl- + Hg2 + +(C2H3O2-)2 --------à Hg2Cl2(s) + NH4+ + C2H3O2-
The precipitate from the reaction is b. Hg2Cl2(s)
(When NH4Cl reacts with aq Hg2 (C2H3O2)2 yellowish-white precipitate of Hg2Cl2(s) is formed.)
