Question
Which of the following defines oxidation?
- A chemical reaction where a substance loses Hydrogen.
- A chemical reaction where a substance loses oxygen.
- A chemical reaction where a substance loses a metal.
- A chemical reaction where a substance gains a metal.
Hint:
Oxidation is the loss of electrons during a reaction. Also we consider hydrogen as a single electron.
The correct answer is: A chemical reaction where a substance loses Hydrogen.
- Oxidation is the loss of electrons during a reaction by a molecule, atom or ion. Oxidation occurs when the oxidation state of a molecule, atom or ion is increased.
- Also oxidation is defined as addition of oxygen.
- In other words its can be defined as a chemical reaction where a substance loses Hydrogen.
