Give examples and suggest reasons for the following features of the transition metal chemistry: (i) The lowest oxide of transition metal is basic, the highest is amphoteric/acidic.
Explanation The lower oxides are those in which there is at least one oxygen and the other is a transition metal, example: MnO. Metal attached with only one oxide and the oxidation state of the metal is lower, so it acts as a base. Metal with a higher number of oxygen is known as higher oxide and metal has a high oxidation state so it can accept an electron and act as an acid. Due to their acidic nature, metals have the tendency to accept an electron. Final Answer The lower oxides have the tendency to donate an electron so they act as a base and higher oxide with high oxidation state a act as an acid.
