Define the following with an example
a) oxidation
b) Reduction
c) Redox reactions
Answers
Answer:
Oxidation is the loss of electrons or increase in oxidation state of an itom, ion or molecule in a chemical reaction example : 4Fe+3O²+6H²O ans 4Fe (OH) ³
Reduction is a chemical reaction that involves the gaining of electrons by one of the atoms involved in the reaction between two chemicals an example of reduction is when iron reacts to oxygen, forming iron oxides such as those called rust. the iron is oxidized and the oxygen is redused.
An oxidation-reduction reaction is any chemical reaction in which, by obtaining or losing an electron,the oxidation number of molecule, atom,or ion varies. An example of a redox reaction is the formation of hydrogen fluoride. to study the oxidation and reduction of reactants, we should break the reaction down.
Answer:
a) Oxidation:- the process or result of oxidizing or being oxidized. Oxidation is the gain of energy.
An example of a reaction is that between hydrogen and fluorine gas to form hydrofluoric
acid:
H2 + F2 → 2 HF
In this reaction, hydrogen is being oxidized and fluorine is being reduced. The reaction may be better understood if it is written in terms of two half-reactions.
b) Reduction:- the amount by which something is reduced. It is loss of oxygen.
An example of a reduction is when iron reacts with oxygen, forming iron oxides such as those called rust. The iron is oxidized and the oxygen is reduced. This is called redox. A blast furnace reverses that reaction, using carbon monoxide as a reducing agent to reduce the iron.
c) Redox reaction:- Redox is a type of chemical reaction in which the oxidation states of atoms are changed. Redox reactions are characterized by the actual or formal transfer of electrons between chemical species, most often with one species undergoing oxidation while another species undergoes reduction.
An example of a redox reaction is the formation of hydrogen fluoride. To study the oxidation and reduction of reactants, we should break the reaction down.
