This is the basic characteristic of electrolytes that they ionize completely into the solution and therefore readily conducts electricity, while the non electrolytes are not.
So option (a) conduct electricity should be the right answer.

Conductivity of Solutions For Che 2A at RCC Introduction Electrolytes are compounds which conduct electricity when dissolved in water. Strong electrolytes consist of ionic compounds which dissociate completely when dissolved in water, AND molecular compounds which completely ionize when dissolved in water. The reactions below illustrate the dissociation reaction of strong electrolytes: Na (aq) + Cl(aq) но NaCl(s) H30 CaBra(s) HO HCl(e) Ca(aq) + 2Br (aa) H*(aq) + C'(aq) Conductivity is a measure of the ability of water to pass...

What would be the purpose of this lab based on the following information? Colligative Properties II Colligative Property is a property of a solution that depends only on the number of solute molecule present. Osmotic pressure, freezing point depression, boiling point elevation, and vapor pressure lowering are all colligative properties. In today’s lab we will look at three of these properties. Electrolytes are substances that forms ions in solution that conduct electricity. Electrolytes can either be an acid, base or...
