Interpretation Introduction

(a)

Interpretation:

The formula of the compound containing the ions ${\text{K}}^{+}$ and ${\text{I}}^{-}$ is to be determined

Concept Introduction

• Ions combine due to attraction between positive and negative ions to form ionic compounds.
• The ions combine in such a way that the ionic compound formed is electrically neutral.
