Learn how to set up a simple Daniell cell with a salt bridge and measure its EMF for CBSE Class 12 Chemistry practicals. Ace 2025-26 exams! In 1836, Daniell's modification of the simple electrical cell resulted in a longer-lasting source of power. It is known as the Daniell cell. Daniell’s setup isolated the copper and zinc ions from each other, preventing polarization from interrupting the flow of electricity. At the same time, it allowed ions in the electrolyte to move between the two metals, necessary to complete the electrical circuit. Let’s take a look at how this works. Learn what is a Daniell cell, a type of galvanic cell that converts chemical energy into electrical energy. Find out how it works, what are its reactions, functions and frequently asked questions.
