← ScienceWhich outcome occurs when high concentrations of dissolved calcium ions cause destabilization of soap solutions?
A)Soap scum formation accelerates greatly✓
B)Increased micelle solubilization of fats
C)Lower critical micelle concentration occurs
D)Increased solution surface tension results
💡 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.
