Question

Rank these species by their ability to act as an oxidizing agent from best oxidizing agent to best reducing agent.

Ag+
cr3+
sn2+
Na+

Answer

Answer: Order of the species in their decreasing oxidizing agent ability is 

Explanation: Oxidizing agent is defined as the agent which helps the other element to get oxidized and it itself gets reduced. These agents should have a positive value of reduction potentials. More is the positive value, best is the oxidizing agent.

Reducing agents are defined as the agents which helps the other element to get reduced and itself gets oxidized. These agents have a negative value of reduction potentials. The more the negative value, best is the reducing agent.

Reduction potentials of the following elements are:

From the given reduction potentials, the best oxidizing agent is  

and the best reducing agent is 

Order in the decreasing oxidizing agent ability of the species is.
