Question

In $\left[Fe\right(H_{2}O{)}_6]C{l}_3$, six $H_{2}O$ are joined by primary valency (PV) and three $Cl$ are joined by secondary valency (SV).
If true enter 1, else enter 0.

Answer 1

The correct answer is 1.

$\left[Fe\right(H_{2}O{)}_6]C{l}_3$: Three $Cl$ joined by primary valency(PV) and six $H_{2}O$ joined by secondary valency(SV).

The primary valancies are normally ionisable and are satisfied by negative ions.

The secondary valancies are non-ionisable which are satisfied by negative ions or neutral molecules. The secondary valency is equal to the coordination number and is fixed for a metal.
