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

• A. Solubility rules help identify compounds that form covalent bonds, such as ethanol, which acts as a weak electrolyte.
• B. Solubility rules help identify compounds that do not dissociate, such as sucrose, which acts as a weak electrolyte.
• C. Solubility rules help identify compounds that completely dissociate, such as sodium nitrate, which acts as a weak electrolyte.
• D. Solubility rules help identify compounds that partially dissociate, such as barium sulfate, which acts as a weak electrolyte.

Answer: (D)
