Account for the following: (i) Cu^(+) ions are not stable in aqueous solution. (ii) Most of the transition metal ions exhibit paramagnetic behaviour. |

Answer» Solution :(i) `Cu^(+)` is unstable in aqueous solution due to lower hydration energy and higher REDUCTION potential. (ii) The transition elements involve the partial filling of d-subshells. Most of the transition METAL ions have unpaired electrons in d-subshell (from `d^(1 to 10)` ) and THEREFORE they GIVE RISE to paramagnetic character. |
