Question

places rich in limestone and gypsum have hard water. Why?

Answer 1

Answer:

Hard water is formed when water percolates through deposits of limestone, chalk or gypsum which are largely made up of calcium and magnesium carbonates, bicarbonates and sulfates.

Answer 2

QUESTION:-

Places rich in limestone and gypsum have hard water. Why?

ANSWER:-

• Places rich in limestone and gypsum have hard water because Hard water is water that contains a high amount of dissolved minerals which are mostly calcium carbonates which are called limestone (CaCO3) or magnesium carbonates(MgCO3), Calcium chlorides (CaCl2) or Magnesium chlorides( MgCl2) or calcium sulphate (CaSO4) which dihydrates to form gypsum.

• The water hardness depends largely on the places where the water is like groundwater that is in the contact with porous rocks that comprise deposits of limestone or gypsum minerals are very hard.

• Limestone and gypsum are sedimentary rocks that have characteristics of high calcium mineralisation. Limestones are chemically primarily calcium carbonate (CaCO3) and chemically gypsum is mainly dihydrated Calcium sulphate.
