FAQs on Acids, Bases and Salts: General Science UPSC Video Lecture - General Knowledge - SSC CHSL

1. What are acids, bases, and salts?
Ans. Acids, bases, and salts are three types of chemical substances. Acids are sour-tasting substances that release hydrogen ions when dissolved in water, while bases are bitter-tasting substances that release hydroxide ions when dissolved in water. Salts are compounds formed when acids react with bases, resulting in the formation of a neutral substance.
2. How do acids and bases differ from each other?
Ans. Acids and bases differ from each other in terms of their taste, chemical properties, and behavior in water. Acids have a sour taste, turn blue litmus paper red, and react with metals to produce hydrogen gas. On the other hand, bases have a bitter taste, turn red litmus paper blue, and feel slippery to touch. Acids release hydrogen ions when dissolved in water, while bases release hydroxide ions.
3. What are some examples of acids, bases, and salts?
Ans. Some common examples of acids include vinegar (acetic acid), lemon juice (citric acid), and stomach acid (hydrochloric acid). Examples of bases include baking soda (sodium bicarbonate), soap (sodium hydroxide), and milk of magnesia (magnesium hydroxide). Salts such as sodium chloride (table salt) and calcium carbonate (chalk) are also widely used.
4. What are the uses of acids, bases, and salts?
Ans. Acids, bases, and salts have numerous applications in various industries and everyday life. Acids are used in cleaning agents, food preservation, and chemical manufacturing. Bases are used in household cleaning products, soap production, and water treatment. Salts have uses ranging from food seasoning to water softening and chemical production.
5. How do acids, bases, and salts affect our daily lives?
Ans. Acids, bases, and salts play significant roles in our daily lives. Acids in our stomach aid in digestion, while bases in cleaning products help remove stains and dirt. Salts are used to enhance the flavor of food and preserve it. Furthermore, the pH balance of acids and bases is crucial for maintaining the proper functioning of our bodies and the environment.
