Many copper (I) compounds are unstable in aqueous solution and undergo disproportionation. Explain.

The group of compounds that will dissociate partially in aqueous solution is

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

Van't Hoff factor (i) for an aqueous solution of an electrolyte is

A coordination complex compound of cobalt has molecular formula containing five ammonia molecules, one nitro group and two chlorine atoms for one cobalt atom. One mole of this compound produces three mole ions in an aqueous solution. On reacting this solution with excess of silver nitrate solution, two moles of AgCl get precipitated. The formula of this compound would be

What happens when KI solution is added to an aqueous solution of copper sulphate?

a. Name the solvent in which ionic compounds are generally soluble. b. Why are aqueous solution of ionic compounds able to conduct electricity?

Assign reasons for the following: (i) Copper (I) ion is not known in aqueous solution. (ii) Actinoids exhibit greater range of oxidation states than lanthanoids.

How would you Account for the following: (i) Of the d^4 species, Cr^(2+) is strongly reducing while manganese (III) is strongly oxidising, (ii) Cobalt (II) is stable in aqueous solution but in the presence of complexing reagents, it is easily oxidised. (iii) The d^1 configuration is very unstable in ions.
