A) \[Hg{{I}_{2}}\]
B) \[HgI_{4}^{2-}\]
C) \[H{{g}^{2+}}\]
D) \[H{{g}^{+}}\]
Correct Answer: B
Solution :
Key Idea: Nesslers reagent is used to detect presence of \[\text{N}{{\text{H}}_{\text{4}}}^{\text{+}}\]ions in inorganic salt analysis. Nesslers reagent is \[{{\text{K}}_{2}}[Hg{{I}_{4}}]\]and it has \[{{[Hg{{I}_{4}}]}^{2-}}\] ion.You need to login to perform this action.
