What do we call a combination of two or more substances that are mixed but not chemically bonded?
Mixture
Compound
Solution
Element
A mixture is made when two or more substances are combined without chemical bonding, so each keeps its own properties. Mixtures can be separated by physical methods. Ducksters: Mixtures vs Solutions
Which of these best describes a solution?
A uniform mixture of two or more substances
A glass with sand settled at the bottom
A group of elements chemically bonded
A pure chemical element
A solution is a homogeneous mixture where the solute dissolves completely in the solvent, resulting in uniform composition. Britannica: Solution (Chemistry)
Which of the following is an example of a heterogeneous mixture?
Salad with lettuce and tomatoes
Salt dissolved in water
Air (nitrogen and oxygen mixture)
Vinegar (acetic acid in water)
A salad is heterogeneous because you can see and separate the different components. In heterogeneous mixtures, phases or parts are not uniform. Khan Academy: Types of Mixtures
Which of the following is a homogeneous mixture?
Salt water
Trail mix
Granola
Oil and water
Salt water is uniform throughout, making it a homogeneous mixture or solution. All parts are identical in composition. Chemicool: Mixture vs Solution
How can you physically separate a mixture of sand and water?
Filtration
Evaporation
Distillation
Chromatography
Filtration uses a porous barrier (like filter paper) to separate solid sand from liquid water. This is a common physical separation method. Science Kids: Filtration
Which of these is an example of a mixture that is not a solution?
Sand and pebbles
Sugar water
Vinegar
Salt dissolved in water
Sand and pebbles form a simple mixture where the parts remain visible and can be separated by hand or sieving. They do not dissolve. Ducksters: Mixtures vs Solutions
What happens to the parts of a mixture when they are combined?
Each part retains its own properties
They react to form a new substance
They always dissolve
They change into gases
In mixtures, the individual components keep their own physical and chemical properties and do not undergo chemical change. BBC Bitesize: Mixtures
Which tool would help you separate a mixture of salt and water?
Evaporation
Magnet
Filter paper
Chromatography paper
Evaporation removes water by turning it into vapor, leaving the dissolved salt behind. It’s a common method to recover solute. Khan Academy: Separating Mixtures
When salt dissolves in water, what is the dissolved substance called?
Solute
Solvent
Solution
Suspension
The solute is the substance that dissolves in the solvent. In salt water, salt is the solute and water is the solvent. Chem4Kids: Solutions
Which term describes the liquid in which a solute dissolves?
Solvent
Solute
Colloid
Precipitate
The solvent is the medium that dissolves the solute. Water is the most common solvent. BBC Bitesize: Solutes and Solvents
How could you separate a mixture of iron filings and sulfur powder?
Use a magnet
Evaporation
Filtration
Distillation
Iron filings are magnetic and sulfur is not, so a magnet can pull out the iron. This is a simple physical separation method. Science Kids: Separating Iron Filings
What process would you use to get salt from a saltwater solution?
Evaporation
Chromatography
Magnetism
Decantation
Evaporation removes water, leaving salt crystals behind. This is commonly used to harvest sea salt. Ducksters: Evaporation
What do we call a mixture in which particles settle out over time?
Suspension
Solution
Colloid
Alloy
A suspension has larger particles that settle out if left undisturbed, like muddy water. Education Portal: Suspensions vs Solutions
What effect does increasing temperature have on how fast a solid solute dissolves in a liquid solvent?
It dissolves faster
It dissolves slower
It stops dissolving
No effect
Higher temperature increases the kinetic energy of molecules, helping solute particles separate and dissolve more quickly. Khan Academy: Factors Affecting Solubility
What term describes a solution that cannot dissolve any more solute at a given temperature?
Saturated
Dilute
Concentrated
Supersaturated
A saturated solution holds the maximum amount of solute at that temperature; any extra will remain undissolved. ChemGuide: Saturation
Which process separates a liquid mixture by boiling and condensing its parts?
Distillation
Filtration
Evaporation
Magnetism
Distillation uses differences in boiling points to separate liquids; one vaporizes and then condenses. Britannica: Distillation
Why can’t you see sugar after it dissolves in tea?
Sugar molecules disperse uniformly at the molecular level
Sugar turns into gas
Sugar reacts chemically to form tea
Sugar changes color to match tea
When sugar dissolves, its molecules break apart and spread evenly among water molecules, making them invisible to the eye. The sugar is still present, just not visible. Kids Chemistry: Dissolution
What method separates oil and water based on density differences?
Decantation
Centrifugation
Filtration
Magnetic separation
Decantation allows the less dense oil to float on top of water and be poured off. This exploits density differences. Chemicool: Decantation
What does concentration measure in a solution?
Amount of solute per amount of solvent
Boiling point of the solution
Temperature of the solvent
Rate of evaporation
Concentration indicates how much solute is dissolved in a certain amount of solvent or solution. It can be expressed in various units like molarity. CK-12: Concentration
What happens to ionic compounds when they dissolve in water?
They separate into ions
They form covalent bonds
They become suspended solids
They evaporate immediately
Ionic compounds break into their positive and negative ions when they dissolve, allowing the solution to conduct electricity. ChemGuide: Ionic Solutions
What is an alloy?
A homogeneous mixture of metals
A compound made of nonmetals
A suspension of metal in water
A heterogeneous mixture of solids
An alloy is a solid solution or homogeneous mixture of two or more metals (or metals with other elements). Examples include steel and bronze. Britannica: Alloy
What type of mixture is fog, where tiny droplets are dispersed in air?
Colloid
Solution
Suspension
Alloy
Fog is a colloid because small liquid droplets are dispersed in a gas and do not settle out quickly. Britannica: Colloid
Which example best illustrates a colloid?
Milk
Salt water
Sand and water
Air
Milk is a colloid made of fat droplets dispersed in water. The particles are intermediate in size and remain suspended. Chemicool: Colloids
According to Henry’s law, how does increasing pressure affect the solubility of a gas in a liquid?
Solubility increases as pressure increases
Solubility decreases as pressure increases
Pressure has no effect
Gas turns into a solid
Henry’s law states that the solubility of a gas in a liquid is directly proportional to the pressure of the gas above the liquid. This is why sodas are bottled under high pressure. ChemGuide: Henry’s Law
What occurs when a supersaturated solution is disturbed by adding a seed crystal?
Rapid crystallization of the solute
The solution becomes less dense
Solute concentration decreases slowly
Solution changes color
A supersaturated solution contains more solute than normally possible. Adding a seed crystal triggers rapid crystallization as the excess solute precipitates out. LibreTexts: Supersaturation

Cheat Sheet

  1. Difference between Mixtures and Solutions -

    According to the American Chemical Society, a mixture combines two or more substances that retain their individual properties, while a solution is a homogeneous mixture at the molecular level. For example, trail mix shows distinct parts, whereas saltwater looks uniform. Mnemonic tip: "Mix keeps its bits, solution splits into atoms."

  2. Homogeneous vs Heterogeneous Mixtures -

    As outlined by Khan Academy, homogeneous mixtures like sugar dissolved in water appear the same throughout, while heterogeneous mixtures like a salad have visible components. You can often tell by looking or using a simple magnifying lens. Keep it in mind during your mixtures vs solutions quiz!

  3. Solubility and Saturation Concepts -

    The National Oceanic and Atmospheric Administration (NOAA) explains that solubility measures how much solute can dissolve in 100 g of solvent at a set temperature. A saturated solution holds the maximum, and an unsaturated one holds less. Remember: "Heat the beat - warm water dissolves faster!"

  4. Methods of Separation -

    Per resources from MIT OpenCourseWare, physical methods like filtration pick out solids in heterogeneous mixtures, while evaporation or distillation separate solutes and solvents in solutions. For instance, you can isolate salt from seawater by evaporating the water. Recall the acronym F.E.D.: Filtration, Evaporation, Distillation.

  5. Types of Mixtures: Suspensions, Colloids, and Solutions -

    The Royal Society of Chemistry classifies suspensions (e.g., muddy water) with large particles that settle, colloids (e.g., milk) with medium particles that scatter light, and true solutions (e.g., tea). Use the Tyndall effect - shine a flashlight to see colloid particles dance in the beam. Think "S-C-S" from big to small.
