Tim conducted experiments with various aqueous solutions to identify the solution displaying the highest conductivity. The diagram illustrates the equipment he employed, while the table enumerates the aqueous solutions subjected to his testing. Which of the aqueous solutions is most probable to have resulted in the brightest glow of the bulb?

Responses

C12H22O11(aq) because it is a nonelectrolyte
C 12 H 22 O 11 ( aq ) because it is a nonelectrolyte

CH3OH(aq) because it is an electrolyte
CH 3 OH( aq ) because it is an electrolyte

KCl(aq) because it is a strong electrolyte
KCl( aq ) because it is a strong electrolyte

NH3(aq) because it is a weak electrolyte

Answer 1

The solution that is most probable to have resulted in the brightest glow of the bulb is KCl(aq) because it is a strong electrolyte.

Strong electrolytes, like potassium chloride (KCl), completely dissociate into ions in solution, which allows electricity to flow freely, thus producing a brighter glow in the bulb. In contrast, nonelectrolytes like C12H22O11 (sucrose) and weak electrolytes like NH3 (ammonia) do not conduct electricity as well as strong electrolytes.
