Question

oxidation and reduction reaction.with example​

Answer 1

Answer:

The reaction between magnesium metal and oxygen, for example, involves the oxidation of magnesium.

Magnesium metal, for example, was thought to lose electrons to form Mg2+ ions when it reacted with oxygen. By convention, the element or compound that gained these electrons was said to undergo reduction.

Answer 2

Answer:

Oxidation- Reduction reaction

A reaction in which one reactant undergoes oxidation whereas the other gets reduced during the course of reaction are termed as oxidation-reduction reactions or redox reactions. Oxidation refers to the loss of electrons or increase in oxidation state by a molecule, atom, or ion. Reduction refers to the gain of electrons or decrease in oxidation state by a molecule, atom, or ion.

Consider the following redox reaction.

✔Burning sugars, such as glucose (C6H12O6) and the fatty acids in the fats we eat.

C6H12O6(aq) + 6 O2(g) --> 6 CO2(g) + 6 H2O(l)

✔Reaction of Manganese dioxide with hydrochloric acid involves redox reaction.

✔Reaction of zinc oxide and carbon.

ZnO + C --> Zn + CO

✔In this reaction carbon is oxidised to CO and ZnO is reduced to Zn.
