Hardness in Water

Hardness in Water

Hard water is any water that forms a scum with soap. Soft water forms lather with soap.

Hardness is caused by dissolved calcium and magnesium icons (Ca2+ and Mg2+).

Temporary hardness

  • Temporary hardness can be removed by boiling the water.
  • Problems caused by temporary hardness: forms scum (wastes soap), limescale forms in pipes (blocks the pipe) and kettles (wastes heat).

Permanent Hardness

  • Permanent hardness can be removed by icon exchange (deionisation) (this works for temporary hardness too). It cannot be removed by boiling the water.
