FAQs on Acids & Bases Video Lecture - Science & Technology for UPSC CSE

1. What is an acid?
Ans. An acid is a chemical substance that donates protons or hydrogen ions when dissolved in water. It is characterized by a pH value less than 7 and has a sour taste. Acids can react with bases to form salts and water.
2. What is a base?
Ans. A base is a chemical substance that accepts protons or hydroxide ions when dissolved in water. It is characterized by a pH value greater than 7 and has a bitter taste. Bases can react with acids to form salts and water.
3. How do acids and bases react with each other?
Ans. Acids and bases can react with each other in a chemical process known as neutralization. In this reaction, the hydrogen ions from the acid combine with the hydroxide ions from the base to form water. The remaining ions combine to form a salt.
4. What are some examples of common acids and bases?
Ans. Some examples of common acids include hydrochloric acid (HCl), sulfuric acid (H2SO4), and acetic acid (CH3COOH). Common bases include sodium hydroxide (NaOH), calcium hydroxide (Ca(OH)2), and ammonia (NH3).
5. How do acids and bases affect our daily lives?
Ans. Acids and bases play important roles in various aspects of our daily lives. For example, acids are used in the production of fertilizers, cleaning products, and even in the digestion of food in our stomachs. Bases are commonly found in household cleaning products, as well as in the production of soaps and detergents. Additionally, acids and bases are crucial in many industrial processes, such as the production of paper, textiles, and pharmaceuticals.
