Metal ions in water can react with soap to form what? | …

"Scum" - precipitated insoluble salts. It depends what metal ions you''re considering, of course. But If there are calcium or magnesium ions dissolved in the water, and soap is dissolved in the water, you find that the sodium ion at the polar end of the soap molecule is replaced by a calcium or magnesium ion, and what results in a insoluble fatty acid salt. This can be observed as grey deposits

Carbonate chemistry — Science Learning Hub

Calcium carbonate is unusual in that its solubility increases as the temperature of the water decreases. The increased solubility of calcium carbonate in rainwater saturated with carbon dioxide is the driving force behind the erosion of limestone rocks, leading to the formation over long periods of time of caverns, caves, stalagmites and stalactites.
