H2O, or water, is considered a non-electrolyte.
This means that water does not dissociate into ions when it dissolves. Instead, it remains as neutral molecules. Electrolytes are substances that ionize in solution, allowing them to conduct electricity. Strong electrolytes fully dissociate into ions, while weak electrolytes only partially dissociate.
Water can conduct a very small amount of electricity due to its self-ionization, where a tiny portion of water molecules dissociate into hydrogen ions (H+) and hydroxide ions (OH–). However, this is not significant enough to classify water as an electrolyte.
In practical terms, while pure water is a poor conductor of electricity, the presence of dissolved salts or acids can increase its conductivity, but this does not change the classification of water itself.
