Fuel Cell

Fuel Cell

Fuel cell A fuel cell is a device that converts chemical energy into electrical energy in a reaction in which hydrogen is oxidized to produce water. Fuel cells have less heat loss, making them more energy-efficient than conventional fuel systems....

Standard Reduction Potentials

Standard Reduction Potentials

Standard hydrogen electrode A platinum electrode is inserted in a solution with a concentration of H+ of 1M, and hydrogen gas at 25℃ of 1 atm surrounding the platinum electrode is in equilibrium with H+. At this time, the electrode...

Polar Molecule & Nonpolar Molecule

Polar Molecule & Nonpolar Molecule

Polar molecule Polar molecules have polar covalent bonds between their constituent atoms, and the shape of the molecule is asymmetric. Therefore, the centers of positive and negative charges do not coincide. Just as there are poles on both sides of...

Electrolysis of Water

Electrolysis of Water

Electrolysis of Water When electrolysis is performed using a dilute aqueous NaOH solution as an electrolyte, hydrogen gas is generated at the cathode (-), and oxygen gas is generated at the anode (+). The reaction equation is as follows. (+)pole:...

Electric Plating

Electric Plating

Electric Plating Electroplating is a technique of depositing a thin film of another metal on the surface of a metal. (-) The electrode is connected to the object to be plated, (+) The electrode is connected to plating material such...

Activity Series of Metals

Ionization tendency of metal The tendency of metals to lose electrons and become cations is called the ‘ionization tendency.’ The ionization sequence is an ordered list of ionization trends. The greater the metal’s ionization tendency, the easier it is to...
