Question

This list of reduction reactions is a helpful tool for predicting how two metals and metal ions will interact with one another. Which statement about the redox activity series is not correct?

Answers:

A) The redox activity series shows the oxidant potential of metal cations and the reducing-agent potential of metal forms.

B) The redox activity series gives you information about how a metal acts as a reducing agent.

C) As you move down the list, the ability of the metal component to reduce another metal increases.

D) The ability of a metal component to act as an oxidant decreases as you move up the list.

A) The redox activity series shows the oxidant potential of metal cations and the reducing-agent potential of metal forms.

B) The redox activity series gives you information about how a metal acts as a reducing agent.

C) As you move down the list, the ability of the metal component to reduce another metal increases.

D) The ability of a metal component to act as an oxidant decreases as you move up the list.

The Redox Activity Series Ca(aq) 2eCa Na(a)eNa Mg2*(aq) 2e Zn2*(aq) +2eZn Fe2+(aq) + 2e Fe Cu2+(aq) + 2e Cu Ag (aq) eAg O2(9) +4H (aq)+ 4e 2H20 Cl(g) 2e2CI

Explanation / Answer

An activity series is the list of substances ranked in order of relative reactivity. The most active metals are at the top of the table; the least active are at the bottom. Each metal is able to displace the elements below it from solution. i. e. each metal can reduce the cations of metals below it to their elemental forms. The activity series is very useful tool for predicting and explaining the direction of redox reactions. The series ranks metals by oxidation potential. Thus the redox activity series shows the oxidant potential of metal cations and the reducing agent potential of metal forms.

Metals at the top of the series are good at giving away electrons. They are good reducing agents. The reducing ability of the metal increases as you go up the series. Metal ions at the bottom of the series are good at picking up electrons. They are good oxidising agents. The oxidising ability of metal ions increases as you go down the series.

So statement C) As you move down the list , the ability of the metal component to reduce another metal increases, is not correct about redox activity series.
