A Galvanic cell, or Voltaic cell, named after Luigi Galvani, or Alessandro Volta respectively, is an electrochemical cell that derives electrical energy from chemical reactions taking place within the cell. It generally consists of two different metals connected by a salt bridge, or individual half-cells separated by a porous membrane.

An electrolytic cell decomposes chemical compounds by means of electrical energy, in a process called electrolysis; the Greek word lysis means to break up. The result is that the chemical energy is increased. Important examples of electrolysis are the decomposition of water into hydrogen and oxygen, and bauxite into aluminum and other chemicals.

An electrolytic cell is different from a voltaic cell because in an electrolytic cell?

In an electrolytic cell, an external power source is needed to drive a non-spontaneous redox reaction, while in a voltaic cell, the redox reaction is spontaneous and generates electric energy. In an electrolytic cell, the anode is positive and the cathode is negative, whereas in a voltaic cell, the anode is negative and the cathode is positive.

Difference between daniell cell and voltaic cell?

A Daniell cell is a specific type of voltaic cell that utilizes a zinc anode, a copper cathode, and a solution of copper sulfate and zinc sulfate to generate electricity through redox reactions. Voltaic cell is a broad term encompassing any electrochemical cell that converts chemical energy into electrical energy through spontaneous redox reactions. Daniell cell is an example of a voltaic cell.
