(a) OF the ions Ag^(+), Co^(2+) and Ti^(4+), which onewill be coloured in aqueous solutions? ( Atomic nos. : Ag = 47 , Co = 27 ,T I = 22) (b) If each one of the above ionic species is in turn placed in a magnetic field, how will it response and why ? |

Answer» Solution :(a) `Co^(2+)` will be colouredbecause it CONTAINS unpaired ELECTRONS. On the other hand , `Ag^(+)` has COMPLETELY filled 3d subshell and `Ti^(4+)` has empty 3d subshell, THEREFORE, they will be colourless. (b) `Co^(2+)` will be attracted by a magnetic field while`Ag^(+)` and `Ti^(4+)` ioniswill be repelled. |
