question :explain the following terms of Gain or loss of oxygen with two examples each (a) oxidation (b) reduction
Answers
Answer:
OXIDATION:
The term oxidation was originally used to describe reactions in which an element combines with oxygen. Example: The reaction between magnesium metal and oxygen to form magnesium oxide involves the oxidation of magnesium. ... And, each O2 molecule gains four electrons to form a pair of O2- ions.
REDUCTION:
Reduction can be considered as the removal of oxygen, the addition of hydrogen, or the gain of electrons. Removal of oxygen: Metal ores which are oxides are reduced to the metal - this is how iron is made from iron ore. The reducing agent is carbon monoxide.
