biliography of hard and soft water
Answers
Answer:
Biography of Hard Water :-
Hard water is water that has high mineral content (in contrast with "soft water"). Hard water is formed when water percolates through deposits of limestone, chalk or gypsum[1] which are largely made up of calcium and magnesium carbonates, bicarbonates and sulfates.

Hard drinking water may have moderate health benefits. It can pose critical problems in industrial settings, where water hardness is monitored to avoid costly breakdowns in boilers, cooling towers, and other equipment that handles water. In domestic settings, hard water is often indicated by a lack of foam formation when soap is agitated in water, and by the formation of limescale in kettles and water heaters.[2] Wherever water hardness is a concern, water softening is commonly used to reduce hard water's adverse effects.
Biography of Soft Water :-
Soft water is water which has relatively low concentration of calcium carbonate and other ions . It contains less than 85.5 parts per million of calcium carbonate.
The water that lathers with soap easily is called or known as soft water. It describes type of water that contain few or no minerals like calcium (Ca) or magnesium (Mg) ions. The term is usually relative to hard water, which does contain significant amounts of such ions.
Soft water mostly comes from peat or igneous rock sources, such as granite but may also come from sandstone sources, since those sedimentary rocks are usually low in calcium and magnesium.
