Match List-I with List-II and select the correct answer using the code given below the Lists: List - I (Compound) Code: List-II (Use) A. Boric acid 1. Antiseptic B. Citric acid 2. Food Preservative C. Magnesium hydroxide 3. Antacid D. Acetic acid 4. Pickle
A-1, B-2, C-3, D-4
Understanding Compound Uses: Matching List I and List II
The question asks us to match common chemical compounds from List-I with their primary uses listed in List-II. Let's analyze each compound and its typical application.
| List - I (Compound) | List-II (Use) |
| A. Boric acid | 1. Antiseptic |
| B. Citric acid | 2. Food Preservative |
| C. Magnesium hydroxide | 3. Antacid |
| D. Acetic acid | 4. Pickle |
We will examine each item in List-I and find its corresponding use in List-II.
Analyzing Each Compound and Its Use
Let's go through the compounds one by one:
- A. Boric acid (\(\text{H}_3\text{BO}_3\)): Boric acid is known for its mild antiseptic and antifungal properties. It is often used in eyewashes and as a treatment for certain infections. Therefore, Boric acid matches with Antiseptic.
- B. Citric acid (\(\text{C}_6\text{H}_8\text{O}_7\)): Citric acid is a weak organic acid found naturally in citrus fruits. It is widely used as a flavoring agent and preservative in food and beverages due to its acidic nature and ability to inhibit bacterial growth. Thus, Citric acid matches with Food Preservative.
- C. Magnesium hydroxide (\(\text{Mg(OH)}_2\)): Magnesium hydroxide is an inorganic compound. In liquid suspension form, it is commonly known as Milk of Magnesia. It acts as an antacid to neutralize excess stomach acid, providing relief from heartburn and indigestion. It also functions as a laxative. Therefore, Magnesium hydroxide matches with Antacid.
- D. Acetic acid (\(\text{CH}_3\text{COOH}\)): Acetic acid is the main component of vinegar, typically about 5-20% by volume. Vinegar is a common ingredient in pickles, where its acidity helps preserve the food and adds a tangy flavor. Thus, Acetic acid matches with Pickle.
Establishing the Correct Matches
Based on the analysis above, the correct matches are:- A. Boric acid matches with 1. Antiseptic
- B. Citric acid matches with 2. Food Preservative
- C. Magnesium hydroxide matches with 3. Antacid
- D. Acetic acid matches with 4. Pickle
Determining the Correct Code Option
We look for the option that represents the pairing A-1, B-2, C-3, D-4. The options are:- A-1, B-2, C-3, D-4
- A-1, B-3, C-2, D-4
- A-4, B-3, C-2, D-1
- A-4, B-2, C-3, D-1
Revision Table: Compound Uses Summary
| Compound | Chemical Formula | Primary Use from List II | Explanation of Use |
| Boric acid | \(\text{H}_3\text{BO}_3\) | Antiseptic | Mild disinfectant, used in eyewashes, topical treatments. |
| Citric acid | \(\text{C}_6\text{H}_8\text{O}_7\) | Food Preservative | Adds acidity to inhibit microbial growth; found in citrus fruits. |
| Magnesium hydroxide | \(\text{Mg(OH)}_2\) | Antacid | Neutralizes stomach acid; commonly known as Milk of Magnesia. |
| Acetic acid | \(\text{CH}_3\text{COOH}\) | Pickle | Main component of vinegar, used for preservation and flavor in pickles. |
Additional Information on Compound Applications
Many common compounds have multiple uses, but the list provides specific, well-known applications. Understanding the chemical properties of acids and bases helps explain their uses.
- Acids like Citric acid and Acetic acid lower pH, creating an environment unsuitable for many bacteria and molds, thus acting as food preservatives.
- Bases like Magnesium hydroxide neutralize acids, making them effective antacids for excess stomach acid.
- Boric acid's mild antiseptic properties are due to its interaction with cell walls and metabolic processes of microorganisms.
Knowledge of these common chemical substances and their properties is important in everyday life and various industries.
