Question

Why would an aqueous solution of a strong electrolyte conduct electricity better than an aqueous solution of a weak electrolyte? Select one: a. More ions are in solution with a weak electrolyte. b. No ions are in solution with a strong electrolyte. c. More ions are in solution with a strong electrolyte. d. No ions are in solution with a weak electrolyte.

Answer 1

Hello!

An aqueous solution of a strong electrolyte would conduct electricity better than an aqueous solution of a weak electrolyte because more ions are in solution with a strong electrolyte.

A strong electrolyte is a solid that dissociates completely in water. That means that the entirety of the moles of the electrolyte that are dissolved would be in solution as ions. More ions in solution mean more electrical conduction and a strong electrolyte, opposed to a weak electrolyte, will have more ions in solution, and hence more conductivity than the solution of a weak electrolyte. 

Have a nice day!
