Respuesta :
Concentration, water temperature, contact time, water hardness, and pH are considered to be among the most important factors.
High mineral content water is referred to as "hard water" (in contrast with "soft water"). Water percolates through limestone, chalk, or gypsum deposits to create hard water, which is mostly composed of calcium and magnesium carbonates, bicarbonates, and sulfates.
Moderate health advantages of consuming hard water are possible. It can be a serious issue in industrial settings, where water hardness is monitored to prevent expensive failures in boilers, cooling towers, and other water-handling machinery. A lack of froth when soap is agitated in water and the buildup of limescale in kettles and water heaters are common signs of hard water in home settings. Wherever water hardness is an issue, water softening is frequently employed to lessen the negative impacts of hard water.
