Interpretation: To determine the composition of ionic compounds.
Concept Introduction: Ionic bonds hold the positively and negatively charged ions that make up ionic compounds together. Ionic compounds have such a net neutral charge because the opposing charges cancel each other out.
Answer to Problem 42A
The composition of the ionic compound can be determined by the chemical formula or empirical formula of a particular ionic compound.
Explanation of Solution
The empirical formula, which may be described as the simplest formula that determines the lowest whole number values of atoms that occur inside the compound and that informs us about the relative number of each element inside the compound, is used to indicate the composition of an ionic compound.
