This is because when a calcium and magnesium particle react with detergent molecule, the new substance does dissolved in water, so there is no scum.

- When a soap is used in hard water, a solid substance we call scum forms.
- This is because charged calcium and magnesium particles (called ions ) present in the water react with soap to form an insoluble substance. ...
- When scum forms, sodium is replaced with a calcium or magnesium particle.
