1. What are acids and bases?

Ans. Acids and bases are two types of chemical compounds. 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. Acids have a pH value less than 7, while bases have a pH value greater than 7.

2. How do acids and bases react with each other?

Ans. When an acid and a base react, they undergo a chemical reaction known as neutralization. During neutralization, the hydrogen ions (H+) from the acid combine with the hydroxide ions (OH-) from the base to form water (H2O). The remaining ions combine to form a salt.

3. What are some examples of common acids and bases?

Ans. Some common examples of acids include hydrochloric acid (HCl), sulfuric acid (H2SO4), and acetic acid (CH3COOH). Common examples of bases include sodium hydroxide (NaOH), potassium hydroxide (KOH), and calcium hydroxide (Ca(OH)2).

4. How do acids and bases affect the pH scale?

Ans. Acids have a pH value less than 7 and can lower the pH of a solution. Bases have a pH value greater than 7 and can increase the pH of a solution. The pH scale is a measure of the acidity or alkalinity of a substance, with 7 being neutral.

5. What are some common uses of acids and bases?

Ans. Acids are used in various industries for purposes such as cleaning, manufacturing fertilizers, and food preservation. Bases are commonly used in cleaning products, making soaps and detergents, and in the production of paper and textiles.
