Which of the following solutions will have the highest electrical conductance? A) 0.1 M NaCl B) 0.1 M BaCl₂ C) 0.1 M AlCl₃ D) All of these will have the same electrical conductance.

Question

Quizplus · Accepted Answer

AlCl3 dissociates into four ions per formula unit in solution (one Al3+ ion and three Cl- ions), which contributes to a higher total ion concentration compared to NaCl and BaCl2, which dissociate into two and three ions, respectively. Higher total ion concentration results in higher electrical conductance.
