Lesson: Primary Galvanic Cells Chemistry • Third Year of Secondary School

Join Nagwa Classes

Attend live Chemistry sessions on Nagwa Classes to learn more about this topic from an expert teacher!

In this lesson, we will learn how to describe primary cells and explain how they produce electrical energy.

Students will be able to

explain how irreversible redox reactions inside primary cells generate electricity,
describe a mercury cell and the half-equations that generate a cell potential,
describe a hydrogen fuel cell and explain how it operates,
use the half-equations in a hydrogen fuel cell to calculate the cell potential,
list differences between traditional primary cells and fuel cells.
