The separation of ions
Concept Introduction:
Transition element is one which can form one or more stable ions with a partially occupied d-subshell. Most of the transition elements are metals and majority of elements exists in various oxidation states also.
Oxidation state: Oxidation state is a number which depicts that how many electrons gets lost or gained by the respective atom.
Balanced chemical equation: The chemical reaction is considered as balanced if all the type and the number of atoms present in reactant side of the chemical reaction equals to the type and the number of atoms present in the product side of the reaction.
