A substance that, when dissolved in water, produces a solution that conducts electric current very efficiently is called:

a. a strong electrolyte

b. none of these

c. a weak electrolyte

d. an electrical solute

e. a strong ion

a strong electrolyte

Explanation:

Let's look at the meaning of the following terms so we can obtain the right answer by means of elimination.

- Strong Electrolyte : A strong electrolyte is a solution/solute that completely, or almost completely, ionizes or dissociates in a solution. These ions are good conductors of electric current in the solution.

- Weak Electrolyte : A weak electrolyte is an electrolyte that does not completely dissociate in aqueous solution. The solution will contain both ions and molecules of the electrolyte. Weak electrolytes only partially ionize in water (usually 1% to 10%)

- Strong ion : Strong ions are cations and anions that exist as charged particles dissociated from their partner ions at physiologic pH. Thus, these ions are "strong" because their ionization state is independent of pH.

Strong Electrolye fits the condition and hence is the correct option.
