Write the empirical formula for at least four ionic compounds that could be formed from the following ions:

love history [14]

Answer:

$FeSO_{4},FeCH_{3}CO,Fe_{2}(SO_{4})_{3},Fe_{2}(CH_{3}CO)_{3}$

Explanation:

Empirical formula of ionic compound formed by two ions $A^{x+}$ and $B^{y-}$ is $A_{y}B_{x}$ (for $x\neq y$ ) of AB (for x = y)

The above empirical formula is in accordance with charge neutrality principle

Here each cation ( $Fe^{3+}$ and $Fe^{2+}$ ) can form two ionic compounds by combining with two given anions ( $SO_{4}^{2-}$ and $CH_{3}CO^{2-}$ ).

So the four ionic compounds are: $FeSO_{4},FeCH_{3}CO,Fe_{2}(SO_{4})_{3},Fe_{2}(CH_{3}CO)_{3}$
