Grade 5 Mixtures and Solutions Practice Test

Build Grade 5 Science skills with five 10-question practice tests on mixtures, solutions, solutes, solvents, dissolving, concentration, separation methods, and scientific evidence.

Mixtures and Solutions Practice Tests

These Grade 5 Science practice tests help students describe mixtures and solutions using observations and evidence. Students identify solutes and solvents, explain dissolving and concentration, choose physical separation methods, plan fair investigations, and apply conservation of matter.

Skills covered

  • Recognizing mixtures and their component properties
  • Distinguishing solutes, solvents, and solutions
  • Explaining dissolving, concentration, and saturation
  • Predicting how stirring, temperature, and particle size affect dissolving
  • Choosing filtration, evaporation, magnetism, sieving, and chromatography
  • Using fair tests, measurements, and repeated trials
  • Applying conservation of matter to mixtures and solutions

How to use these practice tests

Read the conditions carefully. Ask which substances are present, whether one substance dissolves in another, which property allows separation, and what evidence supports the conclusion. In investigation questions, identify the variable being changed and the result being measured.

1. QuestionMultiple choice

What is a solution?

Please select an answer first.

Correct answer: A

The correct answer is A mixture in which one substance is evenly dissolved in another substance..

  1. Identify the mixture concept: Decide whether the question asks about a mixture, solution, dissolving, concentration, or separation.
  2. Use the evidence: A solution is a uniform mixture formed when one substance dissolves in another.
  3. Choose the best explanation: The correct choice is A mixture in which one substance is evenly dissolved in another substance..

A solution is a uniform mixture formed when one substance dissolves in another.

2. QuestionMultiple choice

In salt water, what is the solute?

Please select an answer first.

Correct answer: B

The correct answer is Salt.

  1. Identify the mixture concept: Decide whether the question asks about a mixture, solution, dissolving, concentration, or separation.
  2. Use the evidence: The solute is the substance that dissolves; in salt water, salt dissolves in water.
  3. Choose the best explanation: The correct choice is Salt.

The solute is the substance that dissolves; in salt water, salt dissolves in water.

3. QuestionMultiple choice

In salt water, what is the solvent?

Please select an answer first.

Correct answer: C

The correct answer is Water.

  1. Identify the mixture concept: Decide whether the question asks about a mixture, solution, dissolving, concentration, or separation.
  2. Use the evidence: The solvent is the substance that does the dissolving; in this example, it is water.
  3. Choose the best explanation: The correct choice is Water.

The solvent is the substance that does the dissolving; in this example, it is water.

4. QuestionMultiple choice

Which observation shows that sugar has dissolved in water?

Please select an answer first.

Correct answer: D

The correct answer is The sugar is no longer visible as separate crystals and the liquid is evenly mixed..

  1. Identify the mixture concept: Decide whether the question asks about a mixture, solution, dissolving, concentration, or separation.
  2. Use the evidence: Dissolved sugar particles spread throughout the water and are not seen as separate crystals.
  3. Choose the best explanation: The correct choice is The sugar is no longer visible as separate crystals and the liquid is evenly mixed..

Dissolved sugar particles spread throughout the water and are not seen as separate crystals.

5. QuestionMultiple choice

What does soluble mean?

Please select an answer first.

Correct answer: A

The correct answer is Able to dissolve in a particular solvent..

  1. Identify the mixture concept: Decide whether the question asks about a mixture, solution, dissolving, concentration, or separation.
  2. Use the evidence: A soluble substance can dissolve in a solvent under suitable conditions.
  3. Choose the best explanation: The correct choice is Able to dissolve in a particular solvent..

A soluble substance can dissolve in a solvent under suitable conditions.

6. QuestionMultiple choice

Which substance is likely to be soluble in water?

Please select an answer first.

Correct answer: B

The correct answer is Table salt.

  1. Identify the mixture concept: Decide whether the question asks about a mixture, solution, dissolving, concentration, or separation.
  2. Use the evidence: Table salt dissolves in water, while the other examples generally do not.
  3. Choose the best explanation: The correct choice is Table salt.

Table salt dissolves in water, while the other examples generally do not.

7. QuestionMultiple choice

Which solution has more solute if both cups contain the same amount of water?

Please select an answer first.

Correct answer: C

The correct answer is The cup with three spoonfuls of sugar..

  1. Identify the mixture concept: Decide whether the question asks about a mixture, solution, dissolving, concentration, or separation.
  2. Use the evidence: With the same amount of solvent, three spoonfuls provide more dissolved solute.
  3. Choose the best explanation: The correct choice is The cup with three spoonfuls of sugar..

With the same amount of solvent, three spoonfuls provide more dissolved solute.

8. QuestionMultiple choice

What happens to the concentration when more water is added to a salt solution?

Please select an answer first.

Correct answer: D

The correct answer is The solution becomes more dilute because the same salt is spread through more water..

  1. Identify the mixture concept: Decide whether the question asks about a mixture, solution, dissolving, concentration, or separation.
  2. Use the evidence: Adding solvent without adding solute lowers the amount of solute per volume.
  3. Choose the best explanation: The correct choice is The solution becomes more dilute because the same salt is spread through more water..

Adding solvent without adding solute lowers the amount of solute per volume.

9. QuestionMultiple choice

What happens when more sugar is added to a solution and it no longer dissolves?

Please select an answer first.

Correct answer: A

The correct answer is The solution has reached its capacity to dissolve sugar under those conditions..

  1. Identify the mixture concept: Decide whether the question asks about a mixture, solution, dissolving, concentration, or separation.
  2. Use the evidence: A solution can dissolve only a certain amount under specific conditions; extra solute remains undissolved.
  3. Choose the best explanation: The correct choice is The solution has reached its capacity to dissolve sugar under those conditions..
