Choose the correct statement related to soaps/detergents-

Options

A. The usage of detergents is environment friendly
B. The cleaning process of soap is more better than detergents because they do better with hard water, while detergents don't
C. Soaps are biodegradable, while detergents are not biodegradables
D. detergents do not pollutes the water

Explanation

To determine the correct statement related to soaps and detergents, we can analyze the properties and characteristics of both substances. Here’s a step-by-step breakdown:

### Step 1: Understand the Composition
- **Soaps** are typically made from natural fats and oils, and they consist of long hydrocarbon chains with a carboxylate group (COO-Na).
- **Detergents** are synthetic and often contain a sulfonate group (SO3-Na) attached to a long hydrocarbon chain.

**Hint:** Remember the chemical structure of soaps and detergents to understand their behavior in different conditions.

### Step 2: Analyze the Interaction with Water
- Soaps do not work well in hard water because the calcium and magnesium ions in hard water can form insoluble salts with the soap, leading to reduced effectiveness.
- Detergents, on the other hand, are designed to work well in hard water and saline conditions because they do not form insoluble salts.

**Hint:** Consider how the presence of ions in water affects the performance of soaps and detergents.

### Step 3: Biodegradability
- Soaps are generally biodegradable, meaning they can be broken down by microorganisms in the environment.
- Many detergents, especially those with branched alkyl chains, are non-biodegradable and can contribute to environmental pollution.

**Hint:** Think about the environmental impact of using soaps versus detergents.

### Step 4: Evaluate the Statements
Now, let's evaluate the statements provided in the question:
1. "The use of detergent is environmentally friendly." - This is misleading as many detergents are non-biodegradable.
2. "The cleaning process of soap is better than detergent." - This is incorrect, especially in hard water conditions.
3. "Soaps are biodegradable while detergents are non-biodegradable." - This is generally true.

**Hint:** Compare the statements with the facts you have learned about soaps and detergents.

### Conclusion
Based on the analysis, the correct statement related to soaps and detergents is: **"Soaps are biodegradable while detergents are non-biodegradable."**
