Soap scum is typically formed when the calcium and magnesium ions found in hard water react with the soap used for cleaning. The reaction produces insoluble compounds that form a scum-like substance. Therefore, option D containing calcium and magnesium is the best choice. The other options, A, B, C, and E, do not typically form soap scum.
