How do solubility rules assist in identifying insoluble ionic compounds like barium sulfate as weak electrolytes?

Solubility rules help identify compounds that form covalent bonds, such as ethanol, which acts as a weak electrolyte.

Solubility rules help identify compounds that do not dissociate, such as sucrose, which acts as a weak electrolyte.

Solubility rules help identify compounds that completely dissociate, such as sodium nitrate, which acts as a weak electrolyte.

Solubility rules help identify compounds that partially dissociate, such as barium sulfate, which acts as a weak electrolyte.
