$anyone \: plz \: thx \: my \: answer$
​

Answer 1

»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.

»Scum builds up on clothes, baths and sinks. Detergents do not form scum.
