Question

Mn 3+ and Co 3+ ions are the strongest oxidising agents in aqueous solution. WHy?

Answer 1

I hope it will help you:)

Answer 2

$Mn 3+$ and $Co3+$ ions are the strongest oxidizing agents in an aqueous solution is because they show the least oxidation state.

Explanation:

• The $Mn3+$ and$Co3+$ can act as a stronger oxidizing agent because their least oxidation state to +2 oxidation state hence act as strong oxidizing agents.
• Electronic configuration of  $Mn$ is $3d5.4s2$
• Electronic configuration of  $Mn 3+$ is $3d4.4s0$
• It is a strong oxidizing agent. A good oxidizing agent reduces itself that is it gains electrons from others.
• Electronic configuration of $Co$ is $3d7,4s2$
• Electronic configuration of $Co3+$ is $3d6,4s0$
• Co3+ is not stable.It is the reason that it likes to go from Co to Co3+
