Interpretation: The empirical formulafor thegiven compounds are to be written.
Concept introduction:
When the formula of an ionic compound is indicated using the smallest whole number ratios without altering the proportion of the atoms of an individual element to form an electrically neutral substance, it is called an empirical formula.
Electrically neutral compounds are formedwhen positive and negative charges on constituent ions balance each other.
While writing the formula of any compound first the valences of the cation and anions are to be written. Then the valency of the cation will be written as the subscript of the anion and vice versa.
