The only cations present in a slightly acidic solutions are $Fe^{3+},\,Zn^{2+}$ and $Cu^{2+}$. The reagent that when added in excess to this solution would identify and separate $Fe^{3+}$ in one step is
$2\,M\,HCl$
$6\,M\,NH_3$
$6\,M\,NaOH$
$H_2S$ gas
Which of the following metals make the most efficient catalyst
Explain why $Cu ^{+}$ ion is not stable in aqueous solutions?
Discuss the magnetic properties of transition elements.
Out of $Cu_2Cl_2$ and $CuCl_2$, which is more stable and why ?
Assertion : Magnetic moment of $Dy$ is highest among lanthanoids.
Reason : Orbital motion contributes magnetic moment.
