Question

The loss of electron is termed as

• A. oxidation
• B. reduction
• C. combustion
• D. neutralization

Answer 1

The Correct Option is A

To understand the concept of electron loss, we need to delve into basic redox (reduction-oxidation) reactions in chemistry.

1. Definition of Oxidation: Oxidation is a chemical process where an atom, molecule, or ion loses one or more electrons. As a result, the oxidation state of the substance increases. This process is commonly summarized by the mnemonic "OIL RIG," which stands for "Oxidation Is Loss" (of electrons).
2. Explanation of Reduction: In contrast, reduction is the gain of electrons by a substance, which decreases its oxidation state. Using the "OIL RIG" mnemonic, "Reduction Is Gain" (of electrons).
3. Assessment of Other Options:
   • Combustion: This is a chemical reaction involving the rapid combination of a substance with oxygen, releasing heat and light. It does not specifically refer to electron loss or gain.
   • Neutralization: A chemical reaction between an acid and a base, producing salt and water. Neutralization does not directly involve the loss or gain of electrons.
4. Given this context, among the provided options, the correct term for the loss of electrons is oxidation.

Therefore, the right answer is oxidation.
