Answer» Correct Answer - B (I)`4Au//Ag(s)+8CN^(-)(aq)+2H_2O(aq)+O_2(g) to 4[Au//Ag(CN)_2]^(-)(aq)+4OH^(-)(aq)` `2[Au//Ag (CN)_2]^(-)(aq)+Zn(s)to2Au//Ag(s)+[Zn(CN)_4]^(2-)(aq)` (II)This method is based on the fact that gangue and ore particles have different degree of wettability with water and pine oil, the gangue particles are preferentially wetted by water while the ore particles are wetted by oil. (III)Electrolytic reduction (Hall-Heroult process) : The purified `Al_2O_3` is mixed with `Na_3AIF_5`(cryolite) or `CaF_2` (fluorspar) which lowers the melting point of the mixture and increases conductivity. The fused matrix is electrolysed. the electrolytic reactions are : Cathode: `Al^(3+)` ("melt")+`3e^(-) to A(l)` `C(s)+2O^(2-)("melt")toCO_2(g)+4e^(-)` (IV) This process is used when metals are reqired in very high purity , for specific application. For example pure Si and Ge are used in semiconductors and hence are purified by this method.Zone refining method is based on the principle that an impure molten metal on gradual cooling will deposit crystals of the pure metal. while the impurities will be left in the remaining part of the molten metal. |

|
Answer» Correct Answer - B::C::D All the metal ion contains `t_(2g).^(6)eg^(0)` configuration so Fe should be in +2 oxidation state and Co in +3 oxidation state but oxygen having tendency to shown different type of oxidation state. [x = oxidation state of `O_(2)]` (A) `[FeCl(CN)_(4)(O_(2))]^(-4)` +2-1-4+x=-4 x=-1 due to the presence of unpatied `e^(-)" in "O_(2)^(-)`, it is an paramagnetic complex. (B) `[Co(CN)_(5)(O_(2))]^(-4)` +3-5+x=-4 x=-2 `O_(2)^(-2)` (diamagnetic) in nature. (C) `Fe^(+2)=t_(2g).^(6)eg^(0)` (diamagnetic) (D) `[Fe(CN)_(5)(O_(2))]^(5-)` +2-5+x=-5,x=-2 `O_(2)^(-2)` (peroxide) is diamagnetic in nature. |

The hexaquo manganese(II) ion contains five unpaired electrons, while the hexacyanoion contains only one unpaired electron. Explain using the crystal field theory. |
| Answer» Mn is `+2` state the configuration `3d^(5)`. In presence of `H_2O` as ligand, the distribution of these five electrons is `t_(2g)^(3)e_(g)^(2)`, i.e., all the electrons remain unpaired. In presence of `CN^(ɵ)` as ligand, the distribution is `t_(2g)^(5)e_(g)^(0)`, i.e., two `t_(2g)` orbitals contain paired electrons while the third `t_(2g)` orbital contains one unpaired electron. | |
