Step-by-step solution for: make a comic strips on chapter acid, base and salt Class 7th ...
Problem Description:
The image depicts a cartoon of two bottles, one red and one blue, engaged in a boxing match. The red bottle is labeled as "Acid" (sour) and the blue bottle as "Base" (slippery). The topic is "Acids and Bases," and the phrase "Sour and slippery" is mentioned.
The task appears to be related to understanding the properties and interactions of acids and bases, as suggested by the visual metaphor of a fight between the two.

Solution and Explanation:
#### 1. Understanding Acids and Bases:
- Acids are substances that donate protons (H⁺ ions) in water. They have a sour taste and can corrode metals. Examples include hydrochloric acid (HCl), sulfuric acid (H₂SO₄), and vinegar (acetic acid).
- Bases are substances that accept protons or donate hydroxide ions (OH⁻) in water. They have a slippery feel and a bitter taste. Examples include sodium hydroxide (NaOH), potassium hydroxide (KOH), and ammonia (NH₃).
#### 2. Properties of Acids and Bases:
- Acids:
- Sour taste.
- Turns blue litmus paper red.
- Low pH (below 7).
- Reacts with metals to produce hydrogen gas.
- Bases:
- Slippery feel.
- Turns red litmus paper blue.
- High pH (above 7).
- Neutralizes acids.
#### 3. The Visual Metaphor:
- The red bottle (acid) is labeled as "sour," which aligns with the characteristic sour taste of acids.
- The blue bottle (base) is labeled as "slippery," which aligns with the characteristic slippery feel of bases.
- The boxing match symbolizes the chemical reaction between acids and bases, where they neutralize each other.
#### 4. Neutralization Reaction:
- When an acid reacts with a base, they undergo a neutralization reaction, forming water and a salt.
- General equation:
\[
\text{Acid} + \text{Base} \rightarrow \text{Salt} + \text{Water}
\]
- Example:
\[
\text{HCl (hydrochloric acid)} + \text{NaOH (sodium hydroxide)} \rightarrow \text{NaCl (sodium chloride)} + \text{H}_2\text{O (water)}
\]
#### 5. Why They "Fight":
- The "fight" in the image represents the chemical battle between acids and bases. In reality, when they react, they cancel out each other's properties:
- The sourness of the acid is neutralized.
- The slipperiness of the base is neutralized.
- The result is a more neutral solution with a pH close to 7.
#### 6. Conclusion:
- The image creatively illustrates the fundamental concept of acids and bases through a boxing metaphor. It highlights their opposing properties ("sour" vs. "slippery") and their tendency to neutralize each other when combined.

Final Answer:
The image uses a boxing metaphor to represent the chemical interaction between acids and bases. Acids are characterized by their sour taste, while bases are characterized by their slippery feel. When they react, they neutralize each other, forming water and a salt. This neutralization process is the key takeaway from the image.
\boxed{\text{Acids and bases neutralize each other in a chemical reaction.}}
