1.	Account for the following : (a)CuCl_(2)is more stable than Cu_(2)Cl_(2). (b) Atomic radii of 4d and 5d series elements are nearly same. (c ) Hydrochloric acid is not used in permanganate titrations. or Account for the following : (a) Eu^(2+) is a strong reducing agent. (b) Orange colour of dichromate ion changes to yellow in alkaline medium. (c ) E^(@) ( M^(2+) // M ) valuesfor transiton metals show irregular variation.
Answer» SOLUTION :(a) `Eu^(2+)`can lose electron to FORM more stable `Eu^(3+)` PROPERTY )
