Question

Match list I with list II and select the correct answer using the codes given below the lists List-I List- II ( 1 ) Heavy water ( A ) Bicarbonates of M g and C a in water ( 2 ) Temporary hard water ( B ) D 2 O ( 3 ) Soft water ( C ) Sulphates and chlorides of Mg and Ca in water ( 4 ) Permanent hard water ( D ) No foreign ions in water, 1 - b , 2 - a , 3 - d , 4 - c, 1 - b , 2 - a , 3 - c , 4 - d, 1 - b , 2 - d , 3 - c , 4 - a, 1 - c , 2 - d , 3 - b , 4 - a

MARKS App · Accepted Answer

Heavy water is D 2 O ( 1 - b ) Temporary hard water contains bicarbonates of C a 2 + and M g 2 + ( 2 - a ) Soft water may have no foreign ions ( 3 - d ) . Permanent hard water contains sulphates and chlorides of C a + 2 and M g 2 + ( 4 - c )

	List-I		List- II
$(1)$	Heavy water	$(A)$	Bicarbonates of $M g$ and $C a$ in water
$(2)$	Temporary hard water	$(B)$	$D_{2} O$
$(3)$	Soft water	$(C)$	Sulphates and chlorides of Mg and Ca in water
$(4)$	Permanent hard water	$(D)$	No foreign ions in water
