The result was that H₂SO₄ is a strong electrolyte, NH₃ is a weak electrolyte and sugar is a non-electrolyte.

Explanation:

The experiment will show that the H₂SO₄ solution will light the lightbulb brightly, the NH₃ solution will light it weakly and the sugar solution will not light it at all.

This happens because to light the lightbulb we need free charges moving in the solution. Therefore, the substance that produce more ions will be the best electrolyte.

H₂SO₄ → 2H⁺ + SO₄²⁻

NH₃ + H₂O → NH₄⁺ + OH⁻

Sugar will not generate ions
