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), KI`

Answer

C

Explanation

If both the compounds contain metals in their lower oxidation states, then they can axist together because they can't be reduced by one another, Since `Fe^(2+)` can't be reduced by `Sn^(2+), FeCl_(2)` and `SnCl_(2)` can exist together.
