Question

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

a). PO3−4
b). NH+4
c). Fe3+
d). ClO−3

Answer 1

a. Na₃PO₄

b. NH₄Cl

c. FeCl₃

d. KClO₃

Step-by-step explanation:

a. Sodium tetraoxophosphate(V) Na₃PO₄

3Na⁺ + PO₄³⁻ → Na₃PO₄

b. Ammonium Chloride NH₄Cl

NH₄⁺ + Cl⁻ → NH₄Cl

c. Iron(III)chloride

Fe³⁺ + Cl⁻ → FeCl₃

d. Potassium trioxochlorate(V) KClO₃

K⁺ + ClO₃⁻ → KClO₃
