The pair of compounds that can exist together is:

Options

A. `FeCl_(3), SnCl_(2)`
B. `HgCl_(2), SnCl_(2)`
C. `FeCl_(2), SnCl_(2)`
D. `FeCl_(3), Kl`

Answer

C

Explanation

The compounds with lower oxidation number and which cannot reduced by one another can exist together. Thus, `FeCl_(2)` and `SnCl_(2)` can exist together as `Fe^(2+)` cannot be reduced by `Sn^(2+)`
