Which of the following aqueous solutions would you expect to be the best conductor of electricity at 25 degrees celcius? Explain your answer.

Question

(a) 0.20 M NaCl (b) 0.60 M CH3COOH
(c) 0.25 M HCl (d) 0.20 M Mg(NO3)2

Answer 1

The more ions in the solution would be expected to conduct better. b is a weak acid so we can forget it. a, c, and d ionize 100%. c has more ions (higher concn) than a so it should be greater than a. c has more ions than any so it should conduct the best.

Answer 2

why not d?

Answer 3

Its D.
