explain the following with suitable example-oxidation, reduction, oxidising agent, reducing agent
Answers
Answer:
1. The iron metal is oxidized to form the iron oxide known as rust. Electrochemical reactions are great examples of oxidation reactions. When a copper wire is placed into a solution that contains silver ions, electrons are transferred from the copper metal to the silver ions. The copper metal is oxidized.
2. Examples of Reduction
The copper ion undergoes reduction by gaining electrons to form copper. The magnesium undergoes oxidation by losing electrons to form the 2+ cation. ... The iron oxide undergoes reduction (loses oxygen) to form iron while the carbon monoxide is oxidized (gains oxygen) to form carbon dioxide.
3. In chemistry, an oxidizing agent is a substance that has the ability to oxidize other substances — in other words to accept their electrons. Common oxidizing agents are oxygen, hydrogen peroxide and the halogens.
4. Reducing agent is an element or compound that loses an electron to an electron recipient in a redox chemical reaction. A reducing agent is thus oxidized when it loses electrons in the redox reaction. Reducing agents "reduce" oxidizing agents. Oxidizers "oxidize" reducers.
Answer:
Explanation:
Oxidation : it involves the gain of oxygen
Reduction : it involves gain of hydrogen
Reducing agent : a substance which undergoes oxidation acts as a reducing agent
Oxidizing agent : a substance which undergoes reduction acts as an oxidizing agent
Example : CuO + H2 arrow Cu + H2O
In this example copper loss oxygen this reaction is called reduction reaction
2) in second reactant hydrogen gain oxygen it is called oxidation reaction
3)copper loss oxygen so it is oxidizing agent
4)hydrogen gain oxygen so it is reducing agent
