Study Notes

Types of Electrochemical Cells

An electrolytic cell is a type of electrochemical cell that converts electrical energy into chemical energy.

Components of a Daniel Cell

The salt bridge in a Daniel cell allows ions to flow between the two half-cells, maintaining electrical neutrality.
The salt bridge is typically composed of a gel or paper soaked in a potassium chloride or sodium chloride solution.
The electrodes in a Daniel cell are made of zinc (anode) and copper (cathode).

Function of Components in a Daniel Cell

The zinc rod acts as the anode, where oxidation occurs.
The purpose of an ammeter or voltmeter in a Daniel cell is to measure the electric current or voltage produced by the cell.
In an electrochemical cell, the salt bridge functions to maintain the electrical neutrality of the system.
An electrochemical cell converts chemical energy into electrical energy.
The electrolyte solution in the container with the copper rod in a Daniel cell is typically a copper(II) sulfate solution.
