Explanations: answer key for all 10 questions
- Q1: In salt water, what is the solute?
Answer: Salt
Water is the solvent.
- Q2: What is a saturated solution?
Answer: One that cannot dissolve any more solute
Extra solute stays undissolved.
- Q3: How does temperature usually affect sugar dissolving in water?
Answer: More dissolves in hot water
Gases are the opposite and dissolve better in cold water.
- Q4: Milk is an example of what?
Answer: A colloid
Tiny fat droplets are spread through water.
- Q5: Which method separates sand from water?
Answer: Filtration
Sand stays on the filter paper.
- Q6: How can you get salt back from salt water?
Answer: Evaporation
Salt pans use the Sun's heat.
- Q7: What does distillation separate?
Answer: Liquids by boiling points
It purifies water and makes spirits.
- Q8: Which method separates colored inks?
Answer: Chromatography
Colors travel different distances on paper.
- Q9: An alloy like brass is what kind of mixture?
Answer: A solid solution
Metals are mixed when molten.
- Q10: Air is mainly a mixture of which two gases?
Answer: Nitrogen and oxygen
Nitrogen is about 78%.
Solutions And Mixtures Knowledge Quiz – Mixing and Separating
A mixture contains two or more substances that are not chemically joined. Some mixtures, like sand and water, are easy to see apart, while solutions, like salt water, look uniform because one substance dissolves completely in another.
In a solution, the substance that dissolves is the solute and the substance doing the dissolving is the solvent. Temperature, stirring and particle size affect how fast and how much dissolves. Colloids, like milk, fog and mayonnaise, contain tiny particles that stay spread out.
Scientists separate mixtures using filtration, evaporation, distillation, magnetism and chromatography. These methods purify drinking water, refine oil, extract salt and help forensic scientists analyze inks and drugs.
