Problem Analysis:
The worksheet is about understanding the concepts of
solution,
solute, and
solvent. Let's break it down step by step.

Part II: Label the Pictures
We are given three images and need to label them using the words
Solution,
Solute, and
Solvent from the box.
1.
Image 1: A pile of brown powder (e.g., sugar or coffee powder).
- This is the
Solute because it is the substance that will be dissolved in a solvent.
2.
Image 2: A glass of clear water.
- This is the
Solvent because it is the substance that dissolves the solute (e.g., water).
3.
Image 3: A glass of brown liquid (e.g., coffee or sugar solution).
- This is the
Solution because it is the homogeneous mixture formed when the solute dissolves in the solvent.
#### Labels:
- Image 1:
Solute
- Image 2:
Solvent
- Image 3:
Solution

Part III: Complete the Sentences
We need to fill in the blanks using the correct terms related to solutions.
1.
A soluble substance mixed in a solvent will make a _________.
- When a solute dissolves in a solvent, it forms a
Solution.
-
Answer: Solution
2.
Salt is the _________ in saltwater.
- In saltwater, salt is the substance being dissolved, so it is the
Solute.
-
Answer: Solute
3.
Water is the _________ in saltwater.
- In saltwater, water is the substance that dissolves the salt, so it is the
Solvent.
-
Answer: Solvent
4.
Sugar and Coffee Powder are the _________ in Coffee.
- Sugar and coffee powder are the substances being dissolved in the coffee, so they are the
Solute.
-
Answer: Solute
5.
Stirring a Solution makes the solutes dissolve _________.
- Stirring increases the rate at which solutes dissolve, so the blank should be "faster."
-
Answer: faster
6.
To make a solute dissolve faster, we can use _________ water.
- Using hot water increases the kinetic energy of the molecules, making the solute dissolve faster.
-
Answer: hot
7.
The substances in a Solution can be separated through _________.
- Solutions can be separated using methods like filtration, distillation, or evaporation.
-
Answer: filtration/distillation/evaporation (any one is correct)
