Question

Keith sets up an electrical circuit that includes wires, a battery, and a lightbulb. With his teacher's supervision, he carefully connects the wires to a beaker so that the electrical current must travel through a solution in the beaker in order to complete the circuit. Keith runs the circuit twice: once with hydrochloric acid in the beaker, and a second time with sugar water in the beaker. The light bulb lights up only when the hydrochloric acid is in the beaker.

Based on Keith's experiment, it can be determined that hydrochloric acid has a _______ than sugar water.

A. lower conductivity
B. higher conductivity
C. lower pH
D. higher density

Answer 1

(B)higher conductivity
