In fact, it may confer some benefits because it is rich in minerals and reduces the solubility of potentially toxic metal ions such as lead and copper. However, there are some industrial applications where hard water may lead to inefficiencies or damage to containers and pipes. In such instances, water softening methods are used. When water is softened, metal cations are exchanged for sodium ions. The most common technique to determine the hardness of water is by looking at sud formation with soap.
