The oxidation state of
Concept introduction:
The
Oxidation is the process in which either loss of electrons, oxidation number increases, or loss of hydrogen atoms takes place. An element is oxidized, when oxidation number increases.
Reduction is the process in which either gain of electrons, oxidation number decreases, or gain of hydrogen atoms takes place. An element is reduced, when oxidation number decreases.
Oxidation state is also known as oxidation number. It is defined as the numbers which are assign to the elements in a chemical combination and number represents the electrons which an atom can share, lose or gain to form
Therefore, transfer of electrons refers to the oxidation state.

(Note: The equation is not balanced.) Fe2*(aq) + Cr2O (aq) + H*(aq) → Cr*(aq) + Fe3*(aq) + H2O(I) O H20(e) O Fe2(s) O Cr20,2 (aq) O Cr3"(aq) OH (aq)arrow_forward
- (A) if both sentences are true,(B) if both sentences are false,(C) if the first sentence is true but the second is false, and(D) if the first sentence is false but the second is true. 1. In a redox reaction, the oxidation number of iron changed from +2 to +3; thus, sulfur is a reducing agent. In a redox reaction, the oxidation number of nitrogen was unchanged; thus, nitrogen is an oxidant. 2. In a redox reaction, the reducing agent is oxidized and it gains electrons. In a redox reaction, the oxidizing agent is reduced and it gains electrons. 3. Bending stress is also known as flexural stress. The test used in observing the mechanical strength of chocolate is the three-point bend test. 4. The flexural strength of materials may be expressed in Pascals. Magnesium is more reactive than silver; therefore, magnesium corrodes faster than silver with the aid of air, oxygen, and sea water.arrow_forwardi need the answer quicklyarrow_forward(a) Why do transition elements show variable oxidation states?
