Zinc-Carbon Cell

Question 1

What is a zinc-carbon cell and its basic function

Answer 1

A zinc-carbon cell is a primary electrochemical cell that produces electrical energy through a chemical reaction between zinc and carbon. It is commonly used in everyday devices like flashlights and clocks

Question 2

What are the main parts of a zinc-carbon cell?

Answer 2

Zinc (Anode): The negative terminal where oxidation occurs. Zinc metal loses electrons and becomes zinc ions.

Carbon (Cathode): The positive terminal, typically a carbon rod that allows reduction to occur (electrons are gained).

Electrolyte (Ammonium Chloride): A paste that helps conduct ions between the anode and cathode, facilitating the chemical reaction.

Separator: A material that separates the anode and cathode to prevent direct contact while allowing ion flow.

Question 3

What is the function of the zinc (anode) in a zinc-carbon cell

Answer 3

The zinc acts as the negative electrode where oxidation occurs. Zinc atoms lose electrons to form zinc ions, which travel through the electrolyte toward the carbon cathode, producing a flow of electric current.

Question 4

Are there other types of primary cells?

Answer 4

Yes! In addition to the zinc-carbon cell, there are other primary cells such as:

Alkaline cells: Use an alkaline electrolyte, offering higher energy capacity and longer life.

Mercury cells: Contain mercury as the electrolyte and are used in small, specialized devices like hearing aids.
