Litmus solution is extracted from lichens, particularly species like Roccella tinctoria and Lecanora tartarea, known for containing dyes used in producing this solution.
Uses of Litmus Solution:
1. pH Indicator: Litmus solution serves as a widely used pH indicator. It changes color in response to acids or bases. Red litmus turns blue in the presence of a base (alkaline solution), while blue litmus turns red in the presence of an acid.
2. Laboratory Testing: In laboratories, it’s utilized for quick testing of a substance’s acidity or alkalinity by observing the color change when litmus paper is dipped into the solution being tested.
3. Educational Tool: Commonly used in educational settings to demonstrate acid-base concepts, helping students grasp pH and chemical reactions based on color changes.
4. Industrial Quality Control: Litmus solution finds use in various industries, especially in quality control processes. It’s crucial in industries like food production and water treatment to maintain specific pH levels.
In summary, derived from lichens, litmus solution acts as a versatile pH indicator, facilitating identification of substances’ acidic or basic nature in scientific, educational, and industrial realms.
Distilled water is commonly considered neutral, but it can lean towards being slightly acidic or basic based on its exposure to carbon dioxide in the air.

Distilled water is commonly considered neutral, but it can lean towards being slightly acidic or basic based on its exposure to carbon dioxide in the air. To verify the neutrality of distilled water, a few tests can be conducted:
pH Test: Employ a pH test strip or a pH meter to measure the water’s pH. Ideally, distilled water should register close to 7, indicating neutrality. A pH value around 7 confirms its neutral nature.
Litmus Paper Test: Dip red and blue litmus paper into the distilled water separately. If both types of litmus paper remain unchanged in color, the water is neutral. Red litmus turns blue in the presence of a base (alkaline), while blue litmus turns red in the presence of an acid.
Conductivity Test: Distilled water, lacking ions, exhibits poor conductivity. Use a conductivity meter to test its ability to conduct electricity. Minimal or no conductivity suggests the absence of ions, supporting its neutrality.
These methods serve to verify the neutrality of distilled water by ensuring its pH is close to 7 and it lacks significant acidic or basic properties.
Neutralization is a chemical reaction occurring between an acid and a base, culminating in the formation of salt and water.

Neutralization is a chemical reaction occurring between an acid and a base, culminating in the formation of salt and water. Here’s an illustrative example demonstrating neutralization:
Example – Neutralization of Hydrochloric Acid (HCl) with Sodium Hydroxide (NaOH):
1. Reactants:
– Hydrochloric Acid (HCl): An acid rich in hydrogen ions (H⁺).
– Sodium Hydroxide (NaOH): A base releasing hydroxide ions (OH⁻).
2. Chemical Equation: The neutralization reaction is symbolized by the equation:
HCl + NaOH → NaCl + H₂O
– Hydrochloric acid reacts with sodium hydroxide, yielding sodium chloride (salt) and water.
3. Reaction Process:
– HCl disintegrates in water, yielding hydrogen ions (H⁺) and chloride ions (Cl⁻).
– NaOH breaks down in water, producing sodium ions (Na⁺) and hydroxide ions (OH⁻).
– Hydrogen ions (H⁺) from the acid combine with hydroxide ions (OH⁻) from the base, generating water (H₂O).
– The remaining ions amalgamate, creating the salt sodium chloride (NaCl).
4. Result: The reaction yields sodium chloride (NaCl), a neutral salt, and water (H₂O). Consequently, the resultant solution is neutral, approximating a pH of 7.
5. Observation: The reaction may emit heat due to its exothermic nature. In addition, water vapor might form if the reaction occurs in an unsealed container.
This instance exemplifies how the combination of an acid and a base results in neutralization, forming a salt and water, effectively nullifying the acidic and basic properties of the initial substances.

1. pH Testing: Dorji can employ pH test strips or a pH meter to analyze the pH levels of the unlabeled soft drinks. This allows him to identify whether each drink is acidic, basic, or neutral.
2. Customer Preferences:
– Acidic Drink: If a customer requests an acidic drink, Dorji can serve a drink with a pH below 7. Typical acidic drinks like citrus juices or certain carbonated beverages, like cola, tend to have lower pH levels.
– Basic Drink: For customers desiring a basic drink, Dorji can serve a drink with a pH above 7. Drinks such as certain types of mineral water or alkaline water often have higher pH levels.
– Neutral Drink: If a customer prefers a neutral drink, Dorji should serve a drink with a pH close to 7. Pure water or specific sports drinks may have a pH close to neutral.
3. Verification: It’s essential for Dorji to confirm the pH of each drink accurately using reliable pH testing methods to ensure precise matching of the drinks with each customer’s preferences.
By utilizing pH testing to classify the drinks as acidic, basic, or neutral, Dorji can effectively match the beverages with the specific preferences of each customer.
