Yes, H2SO4 (sulfuric acid) is an electrolyte.
Explanation
According to the provided reference, sulfuric acid (H2SO4) is specifically classified as a strong electrolyte. This means it dissociates completely into ions when dissolved in water. The dissociation process is represented as follows:
H2SO4 → 2H+ + SO42-
The presence of these ions (hydrogen ions and sulfate ions) allows the solution to conduct electricity, which is the defining characteristic of an electrolyte. Strong electrolytes, like H2SO4, conduct electricity very efficiently because they produce a high concentration of ions in solution.
