Iron (+II) is one of the most important ...

Iron (+II) is one of the most important oxidation states, and salts are called ferrous salts. Most of the Fe (+II) salts are pale green and contain `[Fe(H_2O)_6]^(2+)` ion. Fe (+II) compounds are easily oxidised by air. and so are difficult to obtain pure `Fe^(2+)` form many complexes like `K_3[Fe(CN)_6]`
Anhydrous `FeCl_2` is made by

A

Heating Fe with dilute HCl

B

Heating Fe with gaseous HCl

C

Reacting Fe with conc.HCl

D

Heating Fe with `Cl_2` gas

Text Solution

Verified by Experts

The correct Answer is:
B
`Fe+HCl (g) rarr FeCl_2 + H_2(g)`
