The minimum equivalent conductance in the fused state is shown by:
Correct answer: B. BeCl₂
- A. MgCl2
- B. BeCl₂
- C. CaCl₂
- D. SrCl₂
Explanation
Due to the small size and high charge density of the Be²⁺ ion, Beryllium chloride (BeCl₂) has a significant degree of covalent character. This means it does not fully dissociate into free ions in the molten state, leading to lower conductivity compared to the more ionic chlorides of the other group 2 metals.

About Electrochemistry
Electrochemistry describes electron transfer through oxidation and reduction, identifies oxidizing and reducing agents, and applies oxidation numbers to balance redox equations. It also covers electrode potential and the standard hydrogen electrode, which provides the reference for comparing the reduction tendencies of other electrodes.
