`{:(,"Column I",,,"Column II"),(1.,"Heavy water",,A.,"Bicarbonates of Mg and Ca in water"),(2.,"Temporary hard water",,B.,"No foreign ions in water"),(3.,"Soft water",,C.,D_(2)O),(4.,"Permanent hard water",,D.,"Sulphates and chlorides of Mg and Ca in water"):}`

A

`1-C,2-D,3-B,4-A`

B

`1-B,2-A,3-C,4-D`

C

`1-B,2-D,3-C,4-A`

D

`1-C,2-A,3-B,4-D`

Text Solution

Verified by Experts

The correct Answer is:
D
Heavy water is `D_(2)O` temporary hardness is due to bicarbonates of Mg and Ca in water, soft water does not contain any foreign ions and permanent hardness is due to sulphates and chlorides of Mg and Ca in water.
