A chemist attempts to protect two pieces of iron by placing them in contact with other substances. The chemist attaches a strip of strontium to one piece of iron and some sulfur to the other. After some time outdoors, one of the iron pieces has rusted, whereas the other has not. Which one rusted? Why? (Hint: Use what you know about metals and nonmetals.)

A chemist attempts to protect two pieces of iron by placing them in contact with other substances. The chemist attaches a strip of strontium to one piece of iron and some sulfur to the other. After some time outdoors, one of the iron pieces has rusted, whereas the other has not. Which one rusted? Why? (Hint: Use what you know about metals and nonmetals.)

Interpretation Introduction

Interpretation:

The rusted piece of iron is to be identified and the reason is to be explained.

Concept Introduction:

Oxidation is the addition of an electronegative element or the removal of an electropositive element in a chemical reaction.

Reduction is the addition of an electropositive element or the removal of an electronegative element in a chemical reaction.

A chemical reaction in which oxidation process and reduction process take place simultaneously is called a redox reaction.

An oxidizing agent is a substance that has the capacity to oxidize the other substances and get reduced in a chemical reaction.

A reducing agent is a substance that has the capacity to reduce the other substances and get oxidized in a chemical reaction.

Non-metals are a better oxidizing agent than metals. They have the capacity to gain electrons and form negative ions. They have the capacity to oxidize the other substances and get reduced.

Metals are a better reducing agent. They have a tendency to lose electrons and form positive ions. They have the capacity to reduce the other substances and get oxidized.

Explanation of Solution

Non-metals are a better oxidizing agent than metals. They have the capacity to gain electrons and form negative ions. They have the capacity to oxidize the other substances and get reduced. An oxidizing agent easily gains electrons. Metals are a better reducing agent. They have a tendency to lose electrons and form positive ions. They have the capacity to reduce the other substances and get oxidized. Sulfur is a non-metal. It is a good oxidizing agent...
