Mixture - Solutions worksheet - Free Printable

To solve this problem, we need to determine whether each item in the images is a mixture (M) or a solution (S). Let's go through each item step by step:

Definitions:

- Mixture: A combination of two or more substances where each substance retains its own properties. The components are not uniformly distributed and can be separated by physical means.
- Solution: A type of homogeneous mixture where one substance (solute) is uniformly dissolved in another substance (solvent). The components are evenly distributed at the molecular level.

Analysis of Each Item:

1. Dish Soap
- Dish soap is a liquid with various ingredients mixed together, but it appears uniform and does not have visible separate components.
- Classification: Solution (S)

2. Cake Ingredients (before blending)
- Before blending, cake ingredients like flour, sugar, and butter are visibly distinct and can be separated.
- Classification: Mixture (M)

3. Sand and shells
- Sand and shells are solid particles that are physically mixed but not chemically combined. They can be separated by physical means.
- Classification: Mixture (M)

4. Lemonade
- Lemonade is a liquid where sugar, lemon juice, and water are uniformly mixed. It is a homogeneous mixture.
- Classification: Solution (S)

5. Syrup
- Syrup is a liquid where sugar is dissolved in water, forming a homogeneous mixture.
- Classification: Solution (S)

6. Coins
- Coins are solid objects made of metal alloys, which are mixtures of different metals. However, they are not solutions because the metals are not uniformly distributed at the molecular level.
- Classification: Mixture (M)

7. Coffee
- Coffee is a liquid where coffee grounds are dissolved in water, forming a homogeneous mixture.
- Classification: Solution (S)

8. Water and Sand
- Water and sand do not mix uniformly; sand settles at the bottom, indicating a heterogeneous mixture.
- Classification: Mixture (M)

9. Chex Mix
- Chex Mix is a combination of cereal pieces, nuts, and other ingredients that are physically mixed but not chemically combined.
- Classification: Mixture (M)

10. Kool-Aid
- Kool-Aid is a liquid where the powdered drink mix is dissolved in water, forming a homogeneous mixture.
- Classification: Solution (S)

11. Trail Mix
- Trail Mix is a combination of nuts, seeds, and dried fruits that are physically mixed but not chemically combined.
- Classification: Mixture (M)

12. Milk
- Milk is a liquid where proteins, fats, and other components are suspended in water, forming a homogeneous mixture.
- Classification: Solution (S)
