Reactions of Iron with Chlorine

The video tutorial explains the reaction between iron and chlorine gas, generated by reacting bleach with concentrated sulfuric acid. Iron is used in the form of steel wool to increase the surface area and reaction rate. The reaction is highly exothermic, causing the iron to glow red hot.

What is the purpose of reacting bleach with concentrated sulfuric acid in this experiment?

• To clean the iron surface

• To generate chlorine gas

• To neutralize the reaction

• To cool down the reaction

Why is steel wool used as the form of iron in this reaction?

• It has a large surface area

• It reacts slower than other forms

• It is easier to handle

• It is cheaper than other forms of iron

How does the large surface area of steel wool affect the reaction?

• It decreases the reaction rate

• It increases the reaction rate

• It has no effect on the reaction

• It makes the reaction safer

What type of reaction occurs when iron reacts with chlorine gas?

• Neutral

• Endothermic

• Exothermic

• Catalytic

What visual effect is observed on iron due to the heat of the reaction?

• It glows red hot

• It turns blue

• It becomes transparent

• It remains unchanged
