If an element is in its highest possibel oxidation state in a compound, it can act as an oxidising agent. If an element is in its lowest possible oxidation state in a compound, if can act as reducing agent. If an element is in the intermediate oxidation state in a compound, it can serve as both oxidising and reducing agent. Based on the above three guidelines, classify the following compounds into three categories and post them in the table given below. KMnO_4 , H_2O_2 , H_2C_2O_4 , FeSO_4 , HCIO_4 , SO_2 , Na_2S_2O_3 , K_2Cr_2O_7

Which element in 3d-series is a strong reducing agent in its +2 oxidation state ? Ti V Cr Mn

Assertion : The maximum oxidation state of chromium in its compounds is +6. Reason : Chromium has only six electrons in ns and (n-1)d orbitals

Assertion : [Ni(CN)_4]^(2-) is square planar and diamagnetic. Reason : It has no unpaired electrons due to presence of strong ligand.

Whenever a reaction between an oxidizing agent and a reducing agent is carried out, a compound of lower oxidation state is formed if the reducing.agent is in excess and a compound of higher oxidation state is formed if the oxidising agent is in excess. Justify this statement giving three illustrations.

Assertion : Reduction of the metal oxide usually involves heating it with some other substance acting as a reducing agent. Reason : The reducing agent combines with the oxygen of the metal oxide.
