I understand why acidic solutions conduct electricity but I am unsure as to what happens when the ions migrate to the electrodes. For example, if there was a solution of NaCl, the Na+ ions will deposit as sodium metal and Cl- ions will form chlorine gas. How about if there was a solution of sulfuric acid? What would happen to the hydronium and sulfate ions when they reach the electrodes?

Hydronium will form Hydrogen

2 H⁺ + 2 e^- => H₂

Depending of the concentration Sulfate will replace Oxygen

2 H₂O + 2 SO₄^2- => 2 H₂SO₄ + O₂ + 4 e^-

or higher concentration it gets  peroxodisulfate

2 SO₄^2- => S₂O₈^2- + 2 e^-

This happens on inert anodes.

If a metal like copper is used the anode will be dissolved.

Cu + SO₄^2- => CuSO₄ + 2 e^-
