Ira is working in a lab with a unknown solution. When he inserts the electrical conductivity tester in the unknown, the bulb begins to glow brightly. Which of these would BEST describe the unknown liquid?

The liquid contains an ionic compound that conducts electricity in solution.

Explanation:

When the bulb glows brightly, it means that the solution is a conductor of electricity. We know this because it allows electrical current flows through it when the plug is submerged in it (I. e. the unknown solution)

This also mean that the solution has high conductivity.

In summary, the bright glow of the bulb resulting from the experiment shows that the current flows easily through the unknown liquid.
