All the following statements are true except |
The hardness of water can be estimated by using EDTA The hardness of water can be removed by using complex salts of sodium metaphosphate Ziegler–Natta catalyst (TiCl3 +R3Al) is a complex used in heterogeneous catalysis in polymerization processes. Dimethyl glyoxime is used in the detection of iron by the formation of the cherry-red complex. |
Dimethyl glyoxime is used in the detection of iron by the formation of the cherry-red complex. |
The answer is (4) Dimethylglyoxime is used in the detection of nickel by the formation of a cherry-red complex. It is not used for the detection of iron. The other statements are all correct. EDTA is a chelating agent that can bind to metal ions, and it is used to estimate the hardness of water. Sodium hexametaphosphate is a complex salt that can also bind to metal ions, and it is used to remove hardness from water. Ziegler–Natta catalyst is a complex used in heterogeneous catalysis in polymerization processes. |
