Question

Chemistry students were testing compounds in an aqueous solution to see which one had the strongest electrical current. There are three beakers each with a different compound. The first beaker and the second beaker lit the light bulbs brightly. The third beaker did not light up the bulb. With the information that is provided, what is the best explanation for the first and second beaker being the strongest electrolytes?
A)The first and second beakers contain a solution that partially dissociates the ions. These ions create an electrical current. The third beaker solution completely dissociates the ions. It is a strong electrolyte.

B)The first and second beakers contain a solution that completely dissociates the ions. These ions create an electrical current. The third beaker solution does not dissociate ions. It is a nonelectrolyte.

C)The first and second beakers contain a solution that does not dissociate ions. These ions create an electrical current. The third beaker solution completely dissociates the ions. It is a strong electrolyte.

D)The first and second beakers contain a solution that completely dissociates the ions. These ions do not create an electrical current. The third beaker solution does completely dissociates the ions. It is a strong electrolyte.

Answer 1

Answer:

B)The first and second beakers contain a solution that completely dissociates the ions. These ions create an electrical current. The third beaker solution does not dissociate ions. It is a nonelectrolyte.

Explanation:

Electrolytes dissociate ions. They are also conductors. Since the first 2 bulbs light up strongly, we can assume that the ions completely dissociated. Since the 3rd did not light up, it is a nonelectrolyte.

Answer 2

Answer:

The first and second beakers contain a solution that completely dissociates the ions. These ions create an electrical current. The third beaker solution does not dissociate ions. It is a nonelectrolyte.
