Reducción

The video tutorial explains the concept of electron gain in chemical reactions, highlighting the process of reduction and oxidation. It discusses how metals like sodium and magnesium act as reducing agents, often stealing oxygen from other compounds. The tutorial provides a foundational understanding of redox reactions and the role of different elements in these processes.

What is the process called when a substance gains electrons in a reaction?

• Oxidation

• Reduction

• Combustion

• Neutralization

In a redox reaction, if one reactant is reduced, what happens to the other reactant?

• It is also reduced

• It is oxidized

• It remains unchanged

• It decomposes

Which of the following metals is known to be a strong reducing agent?

• Gold

• Sodium

• Copper

• Iron

What is the role of reducing agents in a chemical reaction?

• To decrease pressure

• To donate electrons

• To accept electrons

• To increase temperature

Which of the following statements is true about magnesium in redox reactions?

• It is a strong oxidizing agent

• It does not participate in redox reactions

• It is a weak reducing agent

• It readily steals oxygen from other compounds
