Answer 2

The chemical formula for ferric chloride is $FeCl_{3}$ .

• Iron (Fe) has two valencies- +2 and +3. In its +2 state, the Fe ion is called Ferrous ion ($Fe^{2+}$), and in its +3 state it is Ferric ion ($Fe^{3+}$).
• Chlorine gains a single electron to form an anion Chloride ($Cl^{-}$). This gives chlorine a valency of -1.
• While writing the chemical formula for Ferric Chloride, we have to observe the valencies of ferric and chloride ions.
• $Fe^{3+}$ = +3 ; $Cl^{-}$ = -1
• On criss-crossing the valencies of both ions, we get-

        $Fe_{(1)}Cl_{(3)}$

• Ignoring the positive and negative signs, the chemical formula is written as- $FeCl_{3}$ .
