Answer
Brief Explanations:
All of these substances are ionic compounds or strong - acids which ionize in water. HBr is a strong acid that completely dissociates into H⁺ and Br⁻ ions in water. CaBr₂, MgCl₂, and KCl are ionic compounds that break into their respective cations (Ca²⁺, Mg²⁺, K⁺) and anions (Br⁻, Cl⁻) in water. However, HBr is a covalent compound in its pure form but acts as a strong electrolyte in water due to its high degree of ionization. Among these, HBr is a strong acid and ionizes most readily because the H - Br bond is relatively weak compared to the ionic bonds in the other salts, and the polar nature of water helps in the dissociation of HBr into ions.

HBr
