Which outcome occurs when high concentrations of dissolved calcium ions cause destabilization of soap solutions?

💡 Explanation

Soap scum accelerates greatly because hard water ions cause a destabilizing salting out effect, decreasing solubility. This precipitation occurs because the ionic bonds formed become stronger therefore scum appears, rather than the soap remaining soluble.
