General Chemistry: Cell Notation and Cathodic Protection

What is the primary focus of Chad's Prep channel?

• Conducting art workshops

• Teaching advanced mathematics

• Providing stress-free science learning

• Offering language courses

Why is platinum used as an inert electrode in some cell notations?

• It is cheaper than other metals

• It does not participate in the reaction

• It is a non-conductive material

• It reacts with all components

In cell notation, where is the anode typically placed?

• On the right

• In the middle

• Above the cathode

• On the left

What does a single vertical line in cell notation represent?

• An inert electrode

• A phase boundary

• A concentration difference

• A salt bridge

What is the main goal of cathodic protection?

• To make iron more reactive

• To increase the weight of iron

• To prevent iron corrosion

• To oxidize iron

How does cathodic protection prevent rust formation?

• By oxidizing iron

• By reducing oxygen

• By preventing Fe2+ formation

• By increasing temperature

What is a common application of cathodic protection?

• In plastic containers

• In glass windows

• In wooden structures

• In oil pipelines

Why is zinc used in cathodic protection?

• It is a non-metal

• It is cheaper than iron

• It is more easily oxidized than iron

• It is less reactive than iron

What happens to zinc in the cathodic protection process?

• It forms a gas

• It remains unchanged

• It loses electrons

• It gains electrons

What role does iron play in cathodic protection?

• It acts as an inert cathode

• It is oxidized to Fe3+

• It reacts with zinc

• It forms a salt bridge
