soaps do not work well in hard waters. But they can still be effected it large quantities of soap are added to water. Explain wh
Nookie1986 [14]

They can still be effected it large quantities of soap are added to water

because more soap eliminates the effect the minerals in hard water has on

its cleaning capacity.

Hard water contains minerals such as

  • Calcium
  • Magnesium
  • Iron etc.

They reduce the cleaning capacity of the soap. This is why soft water is

preferably used as it doesn't contain these minerals.

When more soap is added, the effect of the minerals reduces thereby

bringing about very little or no effect on the cleaning capacity of the soap.
