Which 1.0 molar solution will be the best conductor of electricity?

Question

(1) NaCl(aq) (2) MgCl2(aq) (3) NaNO3(aq) (4) AlCl(aq)

Answer 1

The best conductor of electricity will be the compound that produces the most ions in solution, given they are all at the same concentration.

NaCl produces 2 ions (Na⁺ and Cl^-)

MgCl₂ produces 3 ions (Mg²⁺ and 2Cl^-)

NaNO₃ produces 2 ions (Na⁺ and NO₃^-)

AlCl₃ (not AlCl) produces 4 ions (Al³⁺ and 3 Cl^-)

Answer would be #4 AlCl₃. I'm sure you have a type since AlCl does not exist. It should be AlCl₃
