Question: is caco3 a strong electrolyte?
Answer: Even insoluble ionic compounds (e.g., AgCl, PbSO4, CaCO3) are strong electrolytes, because the small amounts that do dissolve in water do so principally as ions; i.e., there is virtually no undissociated form of the compound in solution. ... There are virtually no molecules of a strong acid or base in solution, only ions.
