Consider the following:- (1) Hardness of water ⇒ Estimated by Na 2 H 2 EDTA (2) Chlorophyll ⇒ Contain complex of Magnesium (3) Hemoglobin ⇒ Contain coordination compound of iron (4) Vitamin B 12

Question

Consider the following:-

(1) Hardness of water ⇒ Estimated by $Na_{2} H_{2}$ EDTA

(2) Chlorophyll ⇒ Contain complex of Magnesium

(3) Hemoglobin ⇒ Contain coordination compound of iron

(4) Vitamin $B_{12} \Rightarrow$ Contain coordination compound of cobalt

(5) Lead poisoning ⇒ Treated by $CaH_{2}$ EDTA

(6) Inhibit the growth of Tumors ⇒ Coordination compound of platinum is used

(7) Coinage metals ⇒ Belongs to elements of group-11 of long form of modern periodic table

(8) $TiCl_{4}$ with $Al (CH_{3})_{3} \Rightarrow$ Basis of the Ziegler catalysts

(9) Bordeaux mixture $\Rightarrow CuSO_{4} + Ca (OH)_{2}$

TestHub · Accepted Answer

Statements (1) to (4): EDTA estimates water hardness, while chlorophyll, hemoglobin, and Vitamin B₁₂ are well-known coordination complexes of Mg, Fe, and Co respectively.

Statements (5) & (6): Calcium-EDTA chelate is used to treat lead poisoning, and cisplatin (a platinum complex) inhibits tumor growth.

Statements (7) to (9): Coinage metals (Cu, Ag, Au) belong to Group 11, TiCl₄ + Al(CH₃)₃ forms a Ziegler catalyst, and Bordeaux mixture consists of CuSO₄ + Ca(OH)₂.

Conclusion: All nine statements are factually correct, making the number of incorrect matches 0.
