Calcium Carbonate as an Electrolyte

The video explores whether calcium carbonate (CaCO3) is an electrolyte or non-electrolyte. It begins by explaining electrolytes, which dissolve in water to produce ions, allowing the solution to conduct electricity. Calcium carbonate is identified as an ionic compound, but its solubility in water is limited. According to solubility rules, calcium carbonate is mostly insoluble, meaning it dissolves very little in water. As a result, it produces few ions and is classified as a weak electrolyte. The video concludes by summarizing that calcium carbonate is a weak electrolyte due to its limited ion production.
