Soluble and Insoluble Substances activity - Free Printable

Problem Analysis:

The task requires identifying which of the given substances can dissolve in water. The key concepts are:

1. Soluble Substances: These are substances that dissolve in water, forming a homogeneous mixture (solution).
2. Insoluble Substances: These are substances that do not dissolve in water and remain as separate particles.

List of Substances Provided:

- Coffee powder
- Flour
- Ice
- Pepper
- Detergent
- Black Salt
- Cotton
- Dispirin
- Fruit Juice
- Honey
- Butter
- Mud

Solution Approach:

We will analyze each substance to determine whether it is soluble or insoluble in water.

#### 1. Coffee Powder
- Coffee powder dissolves in water, forming a solution.
- Soluble

#### 2. Flour
- Flour does not dissolve in water; instead, it forms a suspension or paste.
- Insoluble

#### 3. Ice
- Ice is solid water and melts to form liquid water when heated. It does not "dissolve" in the traditional sense.
- Not applicable (but since it is water, it doesn't dissolve in water).

#### 4. Pepper
- Pepper does not dissolve in water; it remains as solid particles.
- Insoluble

#### 5. Detergent
- Detergents are designed to dissolve in water to form a solution.
- Soluble

#### 6. Black Salt
- Black salt (Kala Namak) is a type of salt that dissolves in water.
- Soluble

#### 7. Cotton
- Cotton is a fibrous material that does not dissolve in water.
- Insoluble

#### 8. Dispirin
- Dispirin (a brand of aspirin) is a medication that dissolves in water.
- Soluble

#### 9. Fruit Juice
- Fruit juice is already a solution of water and dissolved sugars, acids, and other compounds.
- Soluble

#### 10. Honey
- Honey dissolves in water, forming a homogeneous mixture.
- Soluble

#### 11. Butter
- Butter is a fat that does not dissolve in water; it separates into layers.
- Insoluble

#### 12. Mud
- Mud is a mixture of soil and water but does not dissolve in water; it settles as a suspension.
- Insoluble

Final Answer:

The substances that can dissolve in water are:
- Coffee powder
- Detergent
- Black Salt
- Dispirin
- Fruit Juice
- Honey
