Electrochemical cells Tamil revision mind map built around a labelled Daniell cell diagram: the anode where oxidation occurs and electrons are released versus the cathode where reduction occurs and electrons are accepted, the salt bridge that maintains charge neutrality and the conditions an electrolyte must meet to serve as one, the rules for writing cell notation with anode on the left and double lines for the salt bridge, the formula E cell standard equals E cathode standard minus E anode standard, and a worked example calculating the Daniell cell's standard EMF as plus 1.10 volts.
