Lesson Worksheet: Mixtures Chemistry
In this worksheet, we will practice identifying and describing different types of mixtures and their physical properties.
Q1:
Which of the following best describes a solution?
- AA homogeneous mixture of two or more substances
- BA mixture of any substance with water
- CA heterogeneous mixture of two or more substances
- DThe medium into which a substance can be dissolved
- EThe liquid component of a mixture between two substances
Q2:
Which of the following statements best describes a mixture?
- AA nonchemical combination of two or more substances
- BA chemical combination of two or more substances
- CA substance composed of only one type of atom or molecule
- DThe combination of two substances in different physical states
- EA molecule that is composed of different types of atoms
Q3:
In an experiment, a student added sodium acetate to a fixed volume of water. Eventually, the student reached a point at which no more sodium acetate dissolved. The student then warmed the solution until no crystals of sodium acetate were visible. The solution was then allowed to cool slightly. The diagram below shows the student’s observations.
Which of the following terms describes solution B?
- AColloidal
- BSupersaturated
- CSaturated
- DSupernate
- EUnsaturated
Which of the following terms describes solution C?
- ASupersaturated
- BUnsaturated
- CNonsaturated
- DColloidal
- ESupernate
Q4:
Three different solutions are shown. Which solution contains a strong electrolyte?
- A(B)
- B(A)
- C(C)
Q5:
Which of the following is not an example of a suspension?
- AChalk powder stirred in water
- BSand stirred in water
- CFlour stirred in water
- DSugar stirred in water
Q6:
Which of the following is the most accurate definition of a solution?
- AA solution is a heterogeneous mixture of two substances or more, with different types that depend on the physical state of each solute and the solvent.
- BA solution is a homogeneous mixture of two substances or more, with different types that depend on the physical state of each solute and the solvent.
- CA solution is a homogeneous mixture of two substances or more, with different types that depend on the density of each solute and the solvent.
- DA solution is a heterogeneous mixture of two substances or more, with different types that depend on the density of each solute and the solvent.
Q7:
Fill in the blank: Aqueous sodium chloride can be considered a .
- Astrong electrolyte
- Bnonelectrolyte
- Cweak electrolyte
Q8:
Which of the following is correct when we add sugar to water?
- AThey form a heterogeneous mixture and are called a colloid.
- BThey form a homogeneous mixture and are called a colloid.
- CThey form a heterogeneous mixture and are called a solution.
- DThey form a heterogeneous mixture and are called suspensions.
- EThey form a homogeneous mixture and are called a solution.
Q9:
Fill in the blanks: Atmospheric air is a type of solution in which the physical state of the solute is and the physical state of the solvent is .
- Agas, liquid
- Bgas, gas

- BTable salt and cobalt(II) chloride in kerosene
- CTable salt in water and sugar in kerosene
- DTable salt in kerosene and cobalt(II) chloride in water
- ETable salt and cobalt(II) chloride in water
