FAQs on Acids and Bases Conduct Electricity:Experiment - Acids, Bases and Salts, CBSE, Class 10, Science

1. What is the definition of an acid and a base?
Ans. Acids are substances that release hydrogen ions (H+) when dissolved in water, while bases are substances that release hydroxide ions (OH-) when dissolved in water.
2. How do acids and bases conduct electricity?
Ans. Acids and bases conduct electricity because they contain ions that are free to move in solution. In an acid, the hydrogen ions (H+) can carry an electric current, while in a base, the hydroxide ions (OH-) can carry an electric current.
3. What are some examples of acids and bases?
Ans. Examples of common acids include hydrochloric acid (HCl), sulfuric acid (H2SO4), and acetic acid (CH3COOH). Examples of common bases include sodium hydroxide (NaOH), potassium hydroxide (KOH), and calcium hydroxide (Ca(OH)2).
4. How can we test if a substance is an acid or a base?
Ans. One way to test if a substance is an acid or a base is by using litmus paper. Litmus paper turns blue in the presence of a base and red in the presence of an acid. Another method is to use pH paper, which gives a numerical value indicating the acidity or alkalinity of a substance.
5. What are the properties of acids and bases?
Ans. Acids have a sour taste, turn blue litmus paper red, react with metals to produce hydrogen gas, and have a pH value less than 7. Bases, on the other hand, have a bitter taste, turn red litmus paper blue, feel slippery to the touch, and have a pH value greater than 7.
